I was about to write a long post on how to get the Poulsbo driver working (with 3D) on Debian Squeeze using the native sources (non EMGD) but I guess I will hold on to that (for now) since the kernel component is in the staging trees. I guess once those are stabilized in the kernel, we should be able to do a xserver-xorg-video-psb package for Debian which was the original intend for this bug report over 20 months ago -:) Thanks for posting the LKML link, Mattia!
