This is a bit off-topic, but I agree completely.

I'm not a guru either. Everything seems fine (intel driver, kernel
digital rendering module loaded successfully, uses EXA, no weird custom
settings in xorg.conf).

You may want to try with them on (I believe Xfce also has a checkbox
somewhere). It might be that you're triggering a bug that slows down
only non-composited text rendering.
Other than that, I have no concrete ideas or suggestions. Your options are:
* look for similar bug reports on launchpad.net (better make that
exact bug reports: intrepid + Intel 82946GZ/GL [8086:2972]) and add
a "me too"; alternatively file a bug report on
* try to attract attention from X.org developers somehow (if we're
talking upstream ones, it would work better if you tried to build
and use the latest drivers)
* try a Jaunty live CD and see if it got better or worse
HOST SYSTEM NOT RESPONDING, PROBABLY DOWN. DO YOU WANT TO WAIT? (Y/N)
