Well, NetBSD says:

ofb0: 640 x 480, 8bpp
wsdisplay0 at ofb0
Apple Computer PlanB (undefined subclass 0x00, revision 0x01) at pci1 dev 13 function 0 not configured

and OpenFirmware says

FF83DF08: /chaos@F0000000
FF83FAA8:   /control@B
FF840E60:   /planb@D

Although I hate to say it, LinuxPPC gets this part right, although
that may be because it boots via the MacOS boot loader, causing the
card to be properly initialized?
