Jaunty on Intel i945: Using the CPU for video rendering

Hi!
I'm aware of all the unfortunate problems with Jaunty and the i945 (and related) chipset, but I've tried almost all the fixes out there, but glxinfo still returns an OpenGL rendering string that matches the CPU.

I've tried the EXA and UXA settings in xorg.conf, the intrepid xorg-video-intel driver, the unsupported xorg-video-intel driver, and a few from the x-team and the xorg-edgers drivers, but to no avail.

I haven't tried the pre-release kernel yet as I'm hoping there's another option. Do you know of one?
Thanks in advance.
