I'm currently facing this bug on my system as well:
x86_64, 2.5G, ATI 9600 2xDVI, the latest Dapper (04.02.2006) with Kernel 2.6.15-14-amd64-k8. It is a fresh install from yesterday. Before, I used the radeon driver and everything worked just fine.
Now everything runs fine only for a while, then suddenly the system freezes. I can't provide any log output ... because there is no log output (kmesg).
It seems to be gone once I boot the 2.6.15-14-amd64-server kernel. With this kernel, however, DRI cannot be initialized. Thus I suppose, the problem is related to the ATI fglrx acceleration code ... don't actually know.
