Yes. With it, acceleration is accessed via regular dri module.

Or maybe there are driver problems... I remember that with older ati
drivers and radeon8500 gl2 was slow as hell (50% cpu usage to display
320x240 video without postprocessing on 2ghz cpu).

Right now it's fast, and sometimes faster than gl. I doubt that 9800
supports more colorspaces than 8500, this should be driver problems. Ati
binary drivers for linux are much worse than nvidia ones...

Btw, some interesting benchmarks:
Both gl & gl2 don't support yuv colorspaces. gl supports only rgb24 and
rgb32, but gl2 supports only rgb24 and bgr24 (why?). I didn't test
16-bit rgb colorspaces.

playing 640x480 mpeg4 video. Just decoding (-vo null -vf scale):
cpu usage 5% decoding

"-vo gl -vf scale" (uses rgb32).
"-vo gl -vf format=rgb32"
26% decoding, 14% filters & output
"-vo gl -vf format=rgb24"
23% decoding, 10% filters & output
"-vo gl -vf format=bgr32"
"-vo gl -vf format=bgr24"
fails

"-vo gl2 -vf scale" (uses bgr24).
"-vo gl2 -vf format=bgr24"
8% decoding, 10% filters & output
"-vo gl2 -vf format=rgb24"
24% decoding, 10% filters & output
"-vo gl2 -vf format=rgb32"
"-vo gl2 -vf format=bgr32"
fails
