Update:
Even with 2.2.13pre15, the stock controlfb.c still doesn't detect the
4MB VRAM in my 7500 (I just tried it). I have to hack controlfb.c to get it
to use all 4MB. This is perhaps a bug specific only to the PowerMac 7500/100
as others have reported that all VRAM was detected on their PowerMac's
without making any changes like I've had to do.
