Intelreg dump

It happens mostly while tampering with window - to reproduce I open
chromium-browser with ~30 tabs, then enter/exit full screen few times on
YouTube(HTML5) wideo. On drm-intel-nightly it happens even faster - often while
starting the browser or opening any window.
Started debugging with Ubuntu 4.2 kernel, then Ubuntu mainline 4.5 kernel, then
drm-intel-nightly. 

Issuing:
echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom
cat /sys/devices/pci0000:00/0000:00:02.0/rom > vbios.dump

gives input/output error at second step

cat /sys/class/drm/card0/error
no error state collected

Intel reg dump attached.

Above are relevant to drm-intel-nightly as requested , but stacktrace present
in launchpadbug from ubuntu 4.2 kernel may also be relevant:
