ls -l /dev/dri/

I suspect that for unknown reasons, eudev isn't setting the proper group.

Currently mdev isn't either...Ah, mdev is only looking for the old
directory-free pathnames (card0 instead of dri/card0).
Adding this to mdev.conf should fix it for those who don't need eudev:
dri/*	root:video 0660

There may be a similar oversight in the eudev rules, or there might not.

HTH,
