This may be similar problem that I've seen with similar PPC firmwares:
https://osdn.net/projects/qmiga/wiki/SubprojectAti
https://osdn.net/projects/qmiga/wiki/SubprojectPegasos2#h3-Known.20issues
TLDR; vgabios-ati.bin is compiled for i386 real mode (bacause that's what
gcc can do, real x86 real mode would need something like bcc I think) that
some x86emu can't handle. You can either use Bochs vga bios via romfile
property of the vga emulation or try the option for x86emu when compiling
vgabios-ati.bin (which did not help the firmwares I've tried).
