I am sure I have been there at some point, but I can hardly remember
exactly how I fixed it. I've kinda lost the number of
modular-xorg-server* and mesa-dri* compilations; it's good fun,
anyway.

 You got your /dev/dri/card0 as expected with the right mode?

You followed generally what is in:
http://mail-index.netbsd.org/tech-x11/2007/03/19/0000.html ?

Maybe the following will help you (it did it for me), taken against

I am presently running Xorg7.2+Mesa652+dri on my laptop; the only
problem is I could not get AIGLX to work. Of the more interesting
OpenGL applications available, I got Blender to run accelerated, and
of course BZFlag!

I got even Xorg7.3 + Mesa653+dri working, but for some reason the
server did not recognize the 'vt05' option, which lead to some weird
effects when used with gdm - like sometimes the keyboard attached to
one of the wscons terminals behind... also on occasions some keys got
repeated many times with no reason; this was even running with AIGLX
and Composite and   I was able to try starting Compiz and Beryl; the
latter kinda ran, but gave mostly white background with occasional
window brought in with ALT-Tab; the former did tjhe '--replace' bit
but then refused to continue due to the lack of a particular call.
I've since reverted back to the initial accelerated setup - mainly
because of the problem with the VTs (and also because otherwise I had
to recompile every OpenGL application - that's another story).

I also did that just in case, although I don't believe it made any difference.
