Running todays drt things have changed a bit -

With AGP gart I can now run gltestperf OK, though I suspect this could be by
luck as the "glxgears type perf" is a bit lower than recent kernels @ 800fps so
maybe the (poor) caching is slowing things down a bit and avoiding it.

With PCIE gart, where glxgears is 1200, I still hit the lockup, but now I am
saved by the new GPU reset code.
