First, please make sure that you have very recent -CURRENT, I made some
updates to the agp handling of g33 chipsets recently.  ~600 fps in gears
is not that unreasonable (glxgears is not a benchmark),  I get about 720
- 800 on my 965gm.  The only obvious issue that I see from your logs is
that write combining failed, which would have an impact on performance.
Once we are sure that you are on the latest code, if there are still
issues, we can look into those.  It is also plausible that this is an
issue with mesa handling the g33, but that would likely show up on linux
as well.

Our ports will get xorg-7.4 once 7.1 is released, which will update mesa
to 7.2 as well.  FWIW, even the water plugin is finally working
correctly for me with the update.
