I use only the CUDA volume rendering stuff and I think there was a marked improvement in performance from 256.29 drivers with the PowerMizer/ACPI fix.
In any case in my experience, compiz and compositing in general significantly reduces the the video card performance... so I can live without some transparency if this leads to better video performace
If you need some configuration files such as mine kernel .config for gentoo just ask...
