Neets: After my 2nd attempt, I got the driver to install meaning I can use Heimdall.
Has anyone been reading up on the OC/UV threads? Seems that doing this (changing the kernel to one that's compatible, then setting the OC/UV via a new app) provides a much better battery experience.
Here' are the links. Yes I know, I'm going against my own wish to see links as a hyperlink rather than dumped into the post - shoot me!

Some of the people on the Doc thread are now including their OC/UV settings in their signature which is handy if you want to start out there and tweak further as need be.
Cheers for that - was wanting to OC my SGS but kept forgetting :P
Now got my SGS overclocked to 1280MHz (Stable) - And using the settings in your sig with SetCPU downclocking it to 100MHz-800MHz when the screen is off (plenty) and 200MHz - 1280MHz with the screen on.
I get a score of 1802 in Quadrant Standard which is not too shabby.
