There is a x86 emulator that can execute x86 VGA BIOS code to initialize
your VGA core in U-Boot. It's part of the MAI port so you can look at
that code and port it to your board. It is actually some scitechsoft
code that's been ported to build within U-Boot.
Gabriel Paubert's preploader code also has an x86 real mode emulator
written in PPC assembly that does the same thing, but it may be more
convenient to work with the stuff in U-Boot. It doesn't help that I
can seem to find a current link to the preploader code. Maybe Gabriel
can appear and provide it.
