I forgot to mention...
The X server runs fine, with no GPU spew in dmesg. I can use the web browser and other programs which are not very challenging for the GPU. DOSBox uses some OpenGL, and it runs fine; prboom-plus uses a bit more OpenGL, and it runs OK. Its when I tested 'torcs' that everything ground to a halt. After navigating the torcs menus to start a game, the screen goes black. One time, the screen came back for a moment -- the FPS indicator showed 0.2 frames/sec -- before blacking out again. I was able to get to VT1 with Ctrl-Alt-F1 and kill torcs, and X was running OK again with I attempted to go back to it with Alt-F7.
