Bergje, i looked at your xorg.log and found this line
"Error in I830WaitLpRing(), timeout for 2 seconds"
and found this bug report at xorg bugzilla:
https://bugs.freedesktop.org/show_bug.cgi?id=11847
the buttom line is that the graphic engine hangs,and after disabling dri the problem seems to go away.
try editing the intel device section in xorg.conf to:
Section "Device"
        Identifier "Intel Corporation 82G965 Integrated Graphics
Controller"
        Driver "intel"
        BusID "PCI:0:2:0"
        Option "AccelMethod" "EXA"
        Option "DRI" "false"
EndSection
note that i am not certain adding Option "AccelMethod" "EXA" is nessecery and you should avoid it sense EXA is note suppose to be production ready.
also disabling dri will probably hurt performance but thats better than having no 3d at all.

btw: if the workaround works for you consider telling them your hardware info to try and help xorg developers in finding a solution.
