Pull in a patch from X.Org-current to let X11 run on AMD Geode LX
CPUs in basic VESA mode:
X86EMU: handle CPUID instruction
Starting X on an AMD Geode LX system such as an Alix board with VGA
connector, the Xorg 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. With this patch it 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.
