You know what? It works! Doesn't require -noslices, too (it makes no
difference). CPU usage is at 5% with your patch (4-5%), which is among
the lowest I can get with any video driver.

I never thought about testing it because I thought your patch is like
a simpler version of the original one, and surely simplified version
wouldn't work where original has failed. Seems like I was wrong.

Yep, mine is dual core too. E6600. Anyway since mplayer can't use more
than one core and fglrx driver doesn't seem to use multiple cores too
(e.g. glxgears either uses up to 100% of a single core while X uses 20%
of the other or they can use single core in 80/20 proportion - with
stupid linux scheduler switching between two modes), I'm not sure it
makes too much difference..
