well i have good news
the ones on the intel site are just ones that can be found at http://dri.freedesktop.org/snapshots/
only they're a little old now
i downloaded the latest version of the i915 driver and install worked perfectly.
i don't play games or anything so i can't really say if the video is better but glxgears now gives ~850 fps as compared to 640 without the i915 module loaded.
