Hello list,

Debian Sid today is making life hard for my Xorg server. 

I'm trying to weed through the bug reports and google results, I find
hints to boot with for instance

nomodeset or
radeon.agpmode=1 or

and check the settings in /etc/modprobe/radeon-kms.conf

(currently KMS is enabled. If I disable it, X won't start).

However I'm not entirely sure what any of these 'tweaks' do. Currently,
X starts but every now and then it will start to become unusable
(scrolling so fast, it will make me pass out if I look at it too long).
