chipsets can be probed without OS support as probing them is only
possible using ACPI. One example of this are the HP ZX1/2 chipsets:
previously the code assumed that these chips were present when no other
of the known chipsets could be probed. This assumption brought SGI
Altrix machines with 64 CPUs to a grinding halt.
build fixes for AMD64.
Made shm* functions in the libc_wrapper more standard conformant by setting
errno correctly.
Use xf86ExendedInitInt10() in VBEExtendedInit() to be able to pass flags.
builds with non-gcc compilers that refuse to let you do return
function_that_returns_void(...)
programs/Xserver/hw/xfree86/os-support/shared/sigiostubs.c Remove includes
of xf86drm.h that break non-DRI builds
