Public bug reported:

Sony VAIO VGN-FW140E/H notebook with Intel Mobil Series 4 chipset.   
Centrino 2, 3GB RAM, 1600X900 display with "Full HD 1080p"
I am running the 2.6.30 kernel and the launchpadpaa intel video enhancements steps which utilize the UAX mode.  Here is my entire xorg.conf file, which includes the modifications suggested by the "bleeding edge" configuation.  These enhancements increased my fps in SecondLife from and average of 4fps to an average of 25fps.

**********************
Most applications which use accelerated video work fine:  GoogleEarth, Tux Racer, LinCity-NG, Stellarium, gl-117, FlightSim, Pinballs, Billard-gl and foobillards.

SecondLife works well, except when I take a screen snapshot or attempt
to edit the avatar.  Any editing in SecondLife  is impossible because
the image is too distorted.  The screen snapshot of my avatar in
SecondLife shows the problem and I have attached a pgn file of it.

TORCS runs, but the image is garbled in the same way my SL avatar image
is.

Penumbra's three Linux role playing games are unusable.  Their introductions work fine, but when in the tutorial mode trying to  learn how to grab objects or move them the images are similar to my SL avatar snapshot, only worse.  In the actual game mode the scenes are indecipherable so the games are unplayable.
