Well I have the answer.
It appears to be either a bug with the way wine implements its 32bit to 64bit 3D rendering or with the way the ATI drivers handle 3D requests from 32bit programs.  I suspect the latter, because I was able to run wine on 64bit with proprietary drivers before, and running wine in a 32bit Live CD seems to work.  The rendering is terribly slow on the Karmic CD, but all the graphics renders properly.
I also noticed that the glxinfo reports all the media acceleration features in 32bit mode, but not in 64bit mode.  I will try the Jaunty 32bit CD as well to see if the rendering speed is any better there.  It would seem to indicate that there is definitely an architecture problem with 64bit ATI OSS video drivers at least for the R300 series.  I'm not sure this would affect everyone, but most definitely two cases with built-in laptop video have been reported so far.  Both using the R300 series driver.

Bryce, I think this should be reported upstream.  What is the proper
channels?
