Sorry about that. Some how the patch got dropped by accident. I included 
it now.

The agp code is such a pain. I uploaded a new patch which hopefully 
addresses this issue. Please try this patch.

As a side note I did recieve feedback about the next steps. Intel also 
tried the do GEM/TTM first then release KSM later. It was a maintenance 
nightmare for them. So it best to also do the KMS now. Last night I 
started the work for the mode setting but its not ready for wide testing 
yet. I hope it is possible to get hardware to do wider range testing. 
Especially for KMS.
