Youtube playback is quite good with swfdec on an athlon xp 2600+ and radeon 
9250 machine. I have these options inside Device section of my xorg.conf:

         Option          "AGPMode"               "4"
         Option          "EnablePageFlip"        "true"
         Option          "AccelMethod"           "EXA"
         Option          "AccelDFS"              "true"

cheers,
