Mine [8086:27ae] hangs with UXA or EXA and with Virtualsize 2048 2048
too so I am reverting to using NoAccel too :(

Note that it took like 6 hours before the hang appeared and I was using
internal and external displays in between

# cat /proc/dri/0/gem_objects

No change on 2.6.30-rc3 nor 2.6.29.1 nor downgrading
xserver-xorg-video-intel to 2.6.3 .

That's the backtrace I see when gdb attaching to the machine:
