Two days ago I updated some kernel packages (Archlinux) and fglrx stopped working (it segfaults on X startup), so I decided to give another shot at the open source driver.
So far it's been good, even acceleration works, but i have some issues.
With kms enabled, power management does not work as it corrupts the whole screen and then freezes the computer just after enabling it. I used both of these methods:
With kms disabled, power management works via options in xorg.conf, it's still like 8W more than with fglrx but better than nothing.
The one problem I got is while playing videos with mplayer (smplayer), as the videos play very fast, no matter what output driver I choose for mplayer.
Videos play normally with kms enabled. Any ideas?
Also, there are some drawing errors with window decorations and taskbar icons (KDE) and also with firefox. This happens with kms enabled or disabled.

Code:
echo dynpm > /sys/class/drm/card0/device/power_method
Code:
echo profile > /sys/class/drm/card0/device/power_method echo low > /sys/class/drm/card-0/device/power_profile
