Did you run the VGA BIOS in the coreboot emulator or did you make
sure that only SeaBIOS would run it? Note that the default is
coreboot, which I think is wrong.

OK, so you did have graphics then?

Note that the kernel drivers are often unaware that there exists
anything other than what the factory BIOS does, so when testing
some graphics hardware together with coreboot you have to be prepared
for things not working out of the box. If you fix it, maybe it will
work out of the box for the next person.

Sorry, don't know about that one.
