powernowd in server seed

Hi, guys!

I'm considering adding powernowd to the server seed, which means that it
will be installed by default on server installs (unless you choose the
minimal install method located in the "Modes" menu (press F4 to see it
at the bootsplash)).  If the installed kernel supports the ondemand
scaling governor, powernowd's init script simply tells the kernel to use
that. If for some reason the kernel doesn't support this, it falls back
to the userspace governor, spawns a daemon that monitors cpu usage and
adjusts cpufreq accordingly. The win, of course, is that you'll save
power, money, and the rain forest. :)

Unless anyone objects, I'll file an FFe for this change, or at least
queue it for Intrepid+1.
