Humble Bundle 2 is live: 5 great games, no DRM, pay what you want (ars technica)

The only workaround that worked for me on my Radeon 4650 with the free drivers was abandoning the Linux release of Braid and just running the Windows version under Wine. (I also had to disable post-processing shaders and force the frame rate to 30fps because the r600 driver isn't fast enough to run at the 60fps the game was trying for, but at least it didn't lock up my GPU at any point.)
