Before this it was meaningless to try to mark DisplayModeRec tables
const, since the mode name would be emitted as a pointer to an
anonymous string constant, and therefore would have to be fixed up by
ld.so and so couldn't live in .rodata. With this change the standard
mode lists can live in .rodata, and modes duplicated from them will
have their names filled in on the fly.
FindPCIVideoInfo() function isn't need anymore.
xf86scanpci() is being called only once so we don't need permanent
(static) variables there.
restorePciState() is not used for now (until we find why multiple
cards aren't working).
Formerly the code claimed it could only handle up to 256 visuals, which
was true. Also true, but not explicitly stated, was that it could only
handle visuals with VID < 256. If you have enough screens, and subsystems
that add lots of visuals, you can easily run off the end. (Made worse
because we allocate visual IDs from the same pool as XIDs.) If your app
then chooses a visual > 256, then the Xinerama code would throw BadMatch
on CreateColormap and your app wouldn't start.
With this change, PanoramiXVisualTable is gone. Other subsystems that
were using it as a translation table between each screen's visuals now
use a PanoramiXTranslateVisual() helper.
This reverts commit 3abce3ea2b and
6cbaf15e61.
The memory returned to xf86LoadModule was allocated in doLoadModule, which
calls the respective module's PreInit. As it turns out, input and output
drivers store a pointer to the module elswhere, so freeing it in
xf86LoadModule is a bad idea.
For further reference: hw/xfree86/common/xf86Helper.c
Input drivers: xf86InputDriverList[blah]->module = module;
Output drivers: xf86DriverList[blah]->module = module;
Unloading the module would not look pretty then.
LoadModule() returns the only reference to a fresh piece of memory (a
ModuleDescPtr). Sadly, xf86LoadModules dropped the return value on the floor
leaking memory for each module it loaded.

All the failure paths were very diligent in freeing the "fullpath" temporary
string, but the success case was not. All the content only got strdup()d, so
it's not live memory anymore.

xf86LogInit allocates a piece of memory, stores it in lf. LogInit() will then
effectively strdup it, but lf is never freed again.

We need to start breaking the XKB API to enforce sanity, so drag whichever
headers we need to do so into the server tree, as the client API is set in
stone, being part of Xlib.
After trying to switch from X to VT (or just quit) the video-amd driver
attempts to issue INT 10/0 to go to mode 3 (VGA). The emulator, running
the BIOS code, would then spit out:
c000:0282: A2 ILLEGAL EXTENDED X86 OPCODE!
The opcode was 0F A2, or CPUID; it was not implemented in the emulator.
This simple patch, against 1.3.0.0, handles the CPUID instruction in one of
two ways:
1) if ran on __i386__ or __x86_64__ then it calls the CPUID instruction
directly.
2) if ran elsewhere it returns a canned 486dx4 set of values for
function 1.
This fix allows the video-amd driver to switch back to console mode,
with the GSW BIOS.
Thanks to Symbio Technologies for funding my work, and ThinCan for
providing hardware :)

'Loading foo' is verbosity 3, whereas 'already built-in' is verbosity 0.
This means that gdm's log would just be full of bare 'module already
built-in' messages.
