Okay, I found a solution that seems to work for me. (I will report back here if it fails, but so far so good.)
An updated version of the open source drivers for the card in my laptop works pretty good. There are no weird artifacts, the fan turns off when it is not cooling, and, well, it seems to Just Work. (I am only looking at 2D stuff, I installed Extreme Tux Racer to see how the 3D is and got something like 4 frames per second - it's basically a slideshow.)
Using the PPA for Tormod Volden did seem to install a bunch of other gorp. I don't know if this is good or bad, so it may be worth it to try to install only the xserver-xorg-video-radeonhd package. I noticed that the package for Karmic is actually one version later, so maybe the best thing is to try that:
