There have been some fixes related to 965GM and Chromium made in Mesa master and 10.5 branch.  Can you retry with 10.5 branch?

I've disabled hardware acceleration in Chrome and after three days since last boot everything still works fine (thank you for the hint).

I would like to test 10.5 branch, but Debian packages are 10.4 only and I cannot experiment too much next few days. Is there some easy way how to get deb packages for devel version?
