XFree86 uses vm86() on IA32 cpus and x86emu on other systems to run the
x86 BIOS of the cards.  Only vm86 approach involves the kernel, though
the kernel is not responsible for running the BIOS code itself, only
creating a v86 arena in the process (1MB address space, 16bit regs,
etc) inside which the BIOS code is executed.
