I last tried with 3.1.0 kernel where, using systool command without
passing any options to kernel command line I got:

$ sudo systool -v -m i915
...
    i915_enable_rc6     = "0"
...

So I put the kernel command line option getting now
    i915_enable_rc6     = "1"

But I can try again with current 3.1.1-2.fc16.x86_64 if something changed...
