Thanks for the update!

I got a Gigabyte GA-EG45M-DS2H and I'm willing to help out testing G45 bits.
I know how to compile and install xf86-video-intel and if you explain how to
build/install the GEM stuff I can test that as well. I'm on Intrepid as my base.

If there is any particular xorg.conf options you want me to test just let me
know and I will post xorg_log/stacks/dmesg back.

Currently, even with DRI=false and EXANoComposite I'm getting a CPU spin inside
evict_and_alloc_block() which happens while _gdm_ is starting (it's inside the
AnimCurScreenBlockHandler function). I have not tried to turn off the animated
cursor (not sure how to do it?). I'm attaching gdb+xorglog+dmesg for this config.
