What does 

glxinfo -l|grep GL_MAX_TEXTURE_SIZE

say?

Usually GLX_EXT_texture_from_pixmap not working properly. Which version
of xserver are you building and running xf86-video-ati against? What
does

LIBGL_ALWAYS_INDIRECT=1 glxinfo|grep texture_from_pixmap|wc -l

say? Is compiz running with LIBGL_ALWAYS_INDIRECT=1?

That would be expected with an R300 class card, as the Mesa r300 driver
doesn't really support GART texturing yet.
