Formerly we sized an array with a compile time constant, then initialized
its size to the same constant, but the Linux PCI init code would increase
that "constant". So if you happened to have more than 128 PCI devices,
you'd happily scribble into whatever variables happened to be in .bss
after that array.
Only really fixed for Linux atm. Other OSes will simply (still) fail to
work on video devices above the 128th PCI device.
SourceValidate is used exclusively by the software cursor code to pull the
cursor off of the screen before using the screen as a source operand. This
eliminates the software cursor from the frame buffer while painting the
rotated image though. Disabling this function by temporarily setting the
screen function pointer to NULL causes the cursor image to be captured.

Setting a mode on an unrotated CRTC was causing all of the rotation updates
to be disabled; the loop looking for active rotation wasn't actually looking
at each crtc, it was looking at the modified crtc many times.

I've managed to solve my own bug (#10545) by applying the following
patch to the xserver.
Please apply.
<Conspiracy mode on>
This monitor is "Vista Certified". I wonder if this is a pure coincidence...
<Conspiracy mode off>
With kind regards

Option "Enable" "True" will force the server to enable an output at startup
time, even if the output is not connected. This also causes the default
modes to be added for this output, allowing even sync ranges to be used to
pick out standard modes.

By default, use the screen monitor section for output 0, however, a driver
can change which output gets the screen monitor by calling
xf86OutputUseScreenMonitor.

The entity (device) has a locking SAREA and a master file descriptor
that optionally isn't closed between server generation.
The locking SAREA contains the device hardware lock.
Each DRI screen creates an new SAREA containing the drawable lock,
drawable-and private info, the drawable SAREA.
The first screen optionally shares its drawable SAREA with the
device SAREA.
Default is to close the master descriptor between server generations,
and to share the drawable SAREA of the first screen with the device locking
SAREA. Thus we should (hopefully) have full backwards compatibility.
Mesa changes to support single-device multiple screens are pending.
This Acer monitor reports support for 75hz refresh via EDID, and yet when
that rate is delivered, the monitor does not sync and reports out of range.
Use the existing 60hz quirk for this monitor.

By the time CloseScreen gets called, we can't call ProcessInputEvents, as
the event queue will get unhappy. So just unregister our hooks instantly,
and hope that they don't get called.
xf86SetSingleMode tries to resize all crtcs to match the selected mode. When
a CRTC has no matching mode, it now disables the CRTC (instead of crashing).
Also, poke the RandR extension when xf86SetSingleMode is done so that
appropriate events can be delivered, and so that future RandR queries return
correct information.

/sys/devices reflects the bus topology, and we don't care that much.
Easier (and more reliable) to just look in /sys/bus/pci/devices, which
is a flat view.
When we see an evdev or vmmouse section, assume that it's a mouse, and
don't add a default mouse device. This will break users who have an
evdev keyboard section but no mouse, and want the mouse to get added
by default.
Now, fbcmap_mi.c contains the fb functions which just wrap mi functions.
Previously, these were in fbcmap.c and compiled when XFree86Server was defined.
Now, clients of fbcmap should either use fbcmap.c or fbcmap_mi.c and not worry
about setting the XFree86Server symbol.
Erasing this variable causes some outputs (SDVO on intel) to fail
to be correctly reset at server reset time.

It seems that the changes to X input exposed a problem that wasn't detected
before. The axis clipping code in GetPointerEvents() uses those limits to
constrain the pointer's coordinate range. The max was zero so the pointer
couldn't move.
