can you post your xorg log and the output of lspci -vn so I can add a
quirk for your card?

we've changed the default AGPMode at different times to try and find
the best default.

your distro should set the permissions properly using udev or some
such.  You shouldn't need to add any options to your config.  setting
it as you did allows anyone to use the drm on your computer which can
be a security issue.

Try it and see :)
EXA has seen a lot of infrastructural improvements lately and performs
quite will on newer xservers.
