Subject: [PATCH] OpenBSD support for libpciaccess.

xserver and libpciaccess both need to open /dev/xf86, which can only
be opened once.  I implemented pci_system_init_dev_mem() like Ian
suggested.  This requires some minor changes to the BSD-specific
os-support code.  Since pci_system_init_dev_mem() is a no-op on
FreeBSD this should be no problem.
