It is hard to guess. Does the driver recognize video RAM size
correctly? Is the video RAM accessible? You can test it using
'md 0x80000000', 'mw 0x80000000 0xaa55aa55 1', 'md 0x80000000'
commands. If the video RAM access doesn't work, than the VGA BIOS
boot failed for some reason. Does your ATI card have two display
output connectors? Are these DVI or VGA output connectors? Try to
connect the display to another VGA connector if any.

Best regards,
Anatolij
