Thanks for all this debugging work jean-baptiste. Downgrading the mesa to the old version seems to prove it is indeed a regression in mesa. I've gone ahead and forwarded this upstream:
Please subscribe yourself to that bug in case upstream needs more information or wishes you to test something.
If you would be willing to test one other thing, I notice a number of settings specified in your /etc/X11/xorg.conf. It is possible one of these settings could be interfering with proper mesa operation. If possible it would be helpful if you could try booting with no xorg.conf at all (just move it aside).
If it does not crash with no xorg.conf, then it would be interesting to individually comment out each of the Option lines in the xorg.conf to see which one(s) produce this ill behavior.
