Actually, the 7200 used platinum, which was a really simple chip. The
fbdev driver is still the correct one, tho. You cannot use the built-in
video for OF, because Apple didn't bother to write a driver for
this chipset...

The gc (Grand Central Station) is the Mac equivalent of a SouthBridge
chip. It contains things like ADB, floppy, serial, and other interface
chips. The replacements for this chip in later models had names like
ohare and heathrow. Someone had a sense of humor in the hardware
department at Apple...
