Here's a fun new way I just whipped up for stock ROM users to play around with these and still keep OTAs in working order.
Basically it's a frontend, so put the
latest Adreno-Nexus*.zip package from Qualcomm in the same directory as my zip, then flash my zip instead. It'll do the rest, including resizing systemless SuperSU's su.img so that it can hold the updated drivers, and pushing the su.d script to bind mount all the new drivers on-the-fly during boot.
To disable temporarily you can change /su/su.d/000adrenomount from chmod 755 to 644 and reboot; to uninstall simply delete /su/vendor and /su/su.d/000adrenomount and reboot. You can either do this while booted, or from recovery if you use my SUmount script, linked below.

Odds and Ends thread for more flashable goodness.
