Sorry for the very slow response.

Very nice. One option would be to bisect[1] between those to find the
individual patch that caused the problem.
But first, let's get this upstream. That means:
1. Test a 3.x kernel, from sid or experimental
2. Follow instructions at
http://intellinuxgraphics.org/how_to_report_bug.html
3. Let us know the bug number so we can track it
Thanks much!
