3d hardware acceleration in 945GM chipset - is there any?

I think I have a line on what's screwing up dri.  You were correct -
something was hanging on to it.  I shut the computer off (in
frustration) and when it powered back up, dri was working.  So I ran
the "tremulous test program" and the Xserver hung.  Ctrl-alt-backspace
to kill it.  Then when I restarted the xserver, dri was gone.  The
lsof command found what grabbed it.  So I think I got it.

I'll have to try a few things.  Getting fullscreen apps to run in
multihead mode with dri looks like it gonna take a little more
monkeying around.  But at least the hardware is working.  So far, the
945GM chip looks like it can do pretty cool things.

Thanks all!
