Sorry for the delay. that was a lot of log at look at.

I wonder if that is due to otehr kernel issues. I remember some time ago 
the VIA disk controller was broken and it was corrupting my file system. I 
updated my tree and the problem went away. Currently with 3.1-rcX the 
wireless driver on my via laptop is broken which is why I wasn't in a 
hurry to update the drm tree. I'm going to add some more TTM code soon to 
the tree and I can update it to a newer kernel. This might fix your

Due to so many configurations lets do a few at a time. Currently the most 
important goal is to make sure the default Ubuntu kernel works with trunk 
and the kms_branch. From the logs it looks okay. Are you having the 
keyboard lockups with kms_branch with the default Ubuntu kernel?
