Alex Deucher released 6.6.192 of the Xorg ATI driver.
This is another ati driver RC aimed at server 1.3. It does not
contain randr 1.2 support, but includes a bunch of fixes since the
last RC release. Ati 6.7 will be the last release to support mergedfb
mode. After 6.7, radeon xrandr 1.2 support will be merged into master
from the randr-1.2 branch. Please log all regressions in bugzilla.
It also contains code to enable direct rendering on rs480 with a recent drm.
