This is so cool :-) . I can run glxgears without a computer crash or hang. It runs a bit jerky though, the gears spin for about a second then the computer hangs for a second then the gears start spinning again for a second etc. I attatched a small part of the kmsg.txt to this email (the original one was about 6 mb in size). If you are interested i can send the whole file to you but it looked like it contained the same messages over and over.
