C3 is Supported

active state: C2
default state: C1
bus master activity: ffffffff
states:
C1: promotion[C2] demotion[--] latency[000] usage[01028830]
*C2: promotion[C3] demotion[C1] latency[050] usage[04785987]
C3: promotion[--] demotion[C2] latency[050] usage[00001327]

This is a Dell D600 1.4g. c3 values are low because I have the USB mouse
on right now. (note the fffffff??)

I've tested it with and w/o C3. The difference in the battery lifetime
was only very minmal. I got like maybe 10 mins extra.

I last 2:30 on Linux and 3h on Windows.

Batt Life Sucks..
