Hi,
as I found out in the meantime - the following described problem can be
only worked around when 'Load "dri"' is removed from the server
section, and 'Option "DRI" "true"' is removed from the Device
section. Otherwise:
I've synced my pre-drm-changes 7-STABLE to the latest 7-STABLE. Now the
grafic performance in xorg decreased dramatically. Moving a window or
resizing a window makes me feel sent back 15 years ago ;). I can "see" the
window resizing. The popup of an window is fast, but moving it around or
scrolling... jesus that is what I call slow. Firefox is nearly not usable
for example :(
I wonder what is causing this. I'm using a ATI Radeon HD3850 in it's AGP
version (probably kinda uncommon).

the whole xorg.conf can be found here:

Is this expected to happen with DRI enabled?
