Public bug reported:

Binary package hint: xserver-xorg-video-ati

After I've upgraded my Karmic to Lucid, radeonhd stopped working, so I
started to use the default radeon driver. Previously I've already tried
it, but it never worked perfectly. Now with default config it started
mplayer with xv without problem in native resolution, but when I changed
to fullscreen (or tried totem with rescaled resolution) image started to
be striped, CPU usage growed to 100%, and playback lagged. Then I
started to play with kernel parameters, now with "nofb quiet nosplash"
it works almost good, but it still eats whole capacity of a core, and
playback is lagging a little bit even with a small sized video. Strange
thing, that with 720p the results are the same, and mplayer doesn't
notify me that my computer is too slow to playback this without
framedrop (it does with 1080p videos) Previously with radeonhd this
wasn't a problem even with several running process in the background.
I'm using an 1920x1080 monitor with an Asus M2A-VM mb with integrated
X1200 (RS690). All packages are updated to the latest under Lucid.
