Leann, I was seeing the same thing (hard lockup at login) with 2.6.30-rc2 from the drm-intel-next branch with my patch applied. It could be due to my patch or some other interaction with more recent kernels. I'm trying to reproduce the problem with 2.6.28 now (first the Ubuntu kernel then one with my patch applied), still waiting for the test script to crash my machine though.
