[ltp] X220 power tricks with 3.2 kernel

Currently I'm using i915.i915_enable_rc6=1 which gave me about a 20% -
30% boost in battery performance. Recently with some dist-upgrade I
haven't seen that sort of boost as often (or just haven't been paying
attention).

Anyhow, anyone got any new kernel options to squeeze out more power?
