I tried your patch. The module built an loaded fine. fgl_glxgears gives 
about 515 fps, glxgears about 2500 fps, as with kernel 2.6.13.4.

But now can no longer play Neverwinter Nights. It needs the 32bit mode 
and 32 bit fglrx drivers (I wrote something about it to the list a 
while ago) and cannot use 3d acceleration any more. I get the following 
error:

#v+
libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering
#v-

It is not a permission problem:

With LIBGL_DEBUG=verbose, I get:

This is what I get on my working configuration (2.6.13.4 with 8.18.6):

Any ideas?
