I haven't really maintained this driver for a while, and I'm not
keeping up with the latest in Intel power management.  I get a steady
stream of mail which I don't really do anything useful with; the
cpufreq list seems like a better destination, unless someone wants to
get the mail directly.

Also clean up a couple of ancient comments which don't really apply
anymore (as far as I know, nobody has ever damaged a CPU with this
driver).
