Another Xorg update
After my last Xorg update I've lost the nice ability to log into my KDE. Well, this sucks because I spent a long time compiling kdelibs and friends so I really want to use it.

If you take a look at the Xorg log you'll see X is mad about a "batch buffer thingie".
Error in /var/log/Xorg.0.log: (EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: No such device
Pretty ease to solve this one. Either upgrade your kernel to something like 2.6.36 or better (recommended) or block xf86-video-intel>2.14.
Upgrade your kernel. I was running an old 2.6.32-tuxonice-r7. Upgraded to 2.6.36 and... Welcome back, KDE.
# emerge --sync && emerge --update gentoo-sources
Workaround (if you're in a hurry)
Add this to
# emerge --update x11-drivers/xf86-video-intel
