it's not entirely right. my Dell D505 works like a champ ( with compiz, emerald). the workaround is to add i915 to boot configuration.
this probably loads proper kernel module. beyond that i did not have time between now and then to hook it up to the debugger so there is generic version running on my machine. Linux host 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:27:30 UTC 2010 i686 GNU/Linux there are a few minor bugs. one is there is no DVD play back on totem (this relates to video and codecs) it simply blackscreens when I start totem...
