Bug#462590: quirk table for radeon AGPmode

[Brice Goglin]

Hello,

A quirk table has been added to the radeon driver to autoselect the
right AGPmode when needed. You shouldn't need to add Option "AGPMode" to
xorg.conf anymore to avoid hangs. I reported your configuration when the
table was setup, but it would be nice if you could test that it actually
works for you.

You'll have to build the upstream xf86-video-ati git (see
http://bgoglin.livejournal.com/10936.html for details). And then comment
out "AGPMode" in xorg.conf, restart X, and check in the log that the
driver now selects the right AGPMode automatically.

If it doesn't work, you might want to complain at
https://bugs.freedesktop.org/show_bug.cgi?id=17360 so that they fix the
quirk table.

thanks,
Brice
