Re: Fedora Core 2 - works fine, except freezing in bzflag after 5 minutes
About the kernel: I got rid of the FC2 kernel early on. I might try turning off SMP.
About overheating: Is there a way to use lmsensors (or some other program) to read the temperature, or do I need to hold a thermometer to the card? Opening the cover is going to disturb the temperature.
Oh, and further testing shows that running glxgears will cause the system to crash, although I didn't stay around long enough to see it happen. There's nothing quite as boring as waiting for a crash!
