Last week I've updated mesa to 7.0.3-rc1 (actually git snapshot dated 20080125), including a rebuild of xorg-server and all xf86-video-* drivers that included Mesa 7.0.1. There's still a few packages with included DRI drivers coming from Mesa 7.0.0, does this have a reason? I left them at 7.0.0.
I've been running this new xorg-server on x86_64 with updated intel driver for a week now without noticable problems. Please test other configurations (unichrome/via/openchome and ati mainly and also the non-free fglrx driver if you can).
