Are OldWorld Macs still supported?

If I set my display (AppleVision 1710) to 1024x768x15, the systems gets
stuck at after the following output [just noticed that if I wait long
enough, the system reboots]:

 Welcome to Linux, kernel 2.6.8-1.541

Further testing show that any display mode which is not 24-bits freezes
here (until the system reboots after a few minutes).

Any display mode which is 24-bits depth continues past this to a black
screen with Tux icon, then after about 5 seconds goes totally black (and
doesn't reboot).

It might be something as simple as a corrupt video driver for this
particular system.

Specifying kernel parameter 'text' doesn't help - as the text system
still needs the framebuffer.

YellowDog 3.0 with kernel 2.4.20 runs fine on this machine.

I'm willing to spend some time to help test this - if you have any
concrete items to check, please let me know.

Thanks,
