Using video=radeonfb:off instead of radeon.modeset=0 resulted in a black screen, even when switching to a console.  I had to boot from an install cd in rescue mode to revert.  Using video=ofonly resulted in the same thing.  I also tried video=offb:off and booted to a GUI, but there was still no hardware acceleration.  If it's at all relevant, here is the output of cat /proc/fb (after removing yaboot parameters):

0 ATI Radeon 4c59

Is there anything else I can try?

Thanks,
