Would be nice to test tip/master - it has both that patch included and the latest pageattr-array API (with enablement in AGP drivers) patchset, done by Shaohua Li, based on Dave's original patch.
That patch by itself doesn't help any -- the new set_memory_array_uc() still calls reserve_memtype() for each single page in the array.
