I have a similar issue.

I installed Natty a couple of days ago. When Unity came up, it was sluggish and many apps crashed. I switched to "classic with no effects", and continued setting up stuff. Later I realised that hardware acceleration was not working. I fixed it (don't remember how), and the problems became worse.

Since my idea for this machine is to use it as a media center, I installed many of this apps, and thought that there were buggy, as I could only see blank screens.

Later I realised that not even glxgears works. If I disable KMS, or set LIBGL_ALWAYS_SOFTWARE=1, they work, but so slow that the apps are unusable.

I have already tried installing the propietary drivers, which tell me that my card is unsupported. I installed the X edgers drivers, with no improvement. Tried different xorg.conf tweaks that I found on the 'net, no dice.

As most of these media apps for some reason require 3d accel (stupid shiny effects), I need to make this work.
