Xorg server-1.10.0-3 + drv-intel-2.14.0-3 + fedora 14 =logout/in segmentation failed

[nimnull22]

Dear All.

As long as my 915GM picture quality still is not good enough for long use after all I've done, I thought that loose nothing and upgrade Xorg+everything to server-1.10.0-3 + drv-intel-2.14.0-3 from Fedora 15 repository. I can't say that screen picture became better yet, but I got segmentation fault when I did logout. I use xfce (fedora14)+slim. After logout Slim never starts and Xorg log has seg. failed errors.
I can fill a bag about it, but want to ask here, because may be kernel-2.6.35.11-83.fc14 shouldn't work with Xorg 1.10.

So, what do you think?

Thanks.

P.S.

P.P.S
After some play I found out that it gives seg. fault on LOGOUT. So I can then start xfce with startxfce4 from tty.
