[Bob Brose]

platinumfb: Found Apple Platinum video hardware
platinumfb: Total VRAM = 2MB (0011)
platinumfb: DACula type 0x3c
platinumfb: Monitor sense value = 0x62b, platinumfb:  Using video mode 6 and col
or mode 2.
line_length: a20
Console: switching to colour frame buffer device 80x30
fb0: Apple Platinum frame buffer device
Macintosh non-volatile memory driver v1.1

This is all I get in 2.6.16:
Platinumfb: Found Apple Platinum video hardware

The screen has the boot params on it but is otherwise blank.
Everything else works as normal.
