Yes, you're quite right:
1. I was using Mesa 8.0.4 - not being aware, that there's a need for more
recent version.
2. After adding "ColorTiling2D" "False" everything works fine, "CG Madness"
reached 62 fps.
3. After replacing Mesa 8.0.4 with Mesa 9.0 + GLU (it's excluded by now, had to
be added separately) - everything works fine with or without "ColorTiling2D"
"False". BTW: although on www.x.org radeon pages found an information: "2D
tiled mode can provide significant performance benefits over 1D tiling with 3D
applications.", actually in CG Madness I didn't notice any difference in
performance (no further "boost"), my guess is, that maybe it turns up in some
specific conditions, or with special kind of games/applications (or maybe this
game is just set to keep not more than around 60 fps, which perfectly makes
sense, since more FPS than 50-60 won't offer "more fluent" motion graphics).

Therefore it's not a bug, but my mistake rather. Sorry for bothering, and
thanks for your assistance.
