I would imagine this is due to the way the x86 emulator works. It
expects a memory region from 0x00000 to 0xfffff. In this region the
graphics rom has to sit at 0xc0000 for compatibility issues.
graphics roms are "allowed" to assume they live at 0xc0000.

So we should not change this but instead get caching and c,d,e-seg
writing work correctly and maybe in a standard way/at a standard
position in LinuxBIOS.

This would also allow us to incorporate ADLO or other stuff that allows
booting more OSes.
