I've upgraded kernel and tried to start Xorg (xfce + compiz inside). It crashs with the following backtrace:

This problem was also reported http://bugs.gentoo.org/264252 and it was provided quite a similar backtrace there. That's with:
Probably this exact problem is fixed by newer intel drivers but after I upgraded intel drivers on a newer version I got more problems I'll report in next bug report. If this problem was fixed, could you point us on patch to fix this issue? Thank you.
I've never seen this problem. Could you try upstream code like 2.7.0 and 22.214.171.124 kernel?
Eh, I did that and got bug 21437. Let's keep this bug as needinfo, but anyway, the newer version of xorg I install the more problems I obtain and that's strange since I'm sure you've tested driver. Could you give me some hints, what to play with, to make X11 working again somehow.
Along with testing the current code, please include Xorg.0.log and dmesg when doing so.
I think we can track the issue with server 1.6 at bug#21596, and close this one with server 1.5.
server>=1.6 is preferred for using KMS (which enables UXA and requires server 1.6)
