It probably emulates one of the 'simple' x86 CPU modes (the one the BIOS
runs in), and as such is very limited. If it is the same emulator that's
been discussed on linuxppc-dev a few times, then it's main (only?) use
is for booting x86 firmware on PCI/AGP boards, especially grafic boards.

I'd be _really_ amazed if X had an x86 emulator. AFAIK, the int10 module
is used for access to BIOS code of the board. It uses the int10
mechanism (_very_ x86-platform-specific) to call BIOS functions.
Needless to say, this is of no use on platforms other than x86 (maybe
Alpha, but that's it then...).
