It's completely avoidable. The stub can copy this information to
standard framebuffer info structure. The only missing thing is to apply
patch by cjwatson or mjg59 (I'm not sure now who wrote it) for having an
ID for linear framebuffer which implies no specific hardware (it can be
any) or firmware (coreboot doesn't provide nay additional info or callback).

Please don't apply this patch it will break SeaBIOS booting with VGABIOS.
