I dont have the older kernels anymore so I cant post those outputs.

However, for interest, with the latest kernel ((, and latest xorg-ati driver (xorg-x11-drv-ati-6.10.0-2.fc10.i386) that everything works, except for one noticeable aspect.

starting with "nomodeset", X is snappy in 2D (metacity) and 3D (compiz).

starting with "quiet rhgb", the pretty voot screen comes up, but X is a tad laggy in 2D, and very laggy in 3D. 

Clearly kernel modesetting is interfering here somehow.
