The "old" new powerbooks worked fine, but the "new" new powerbooks weren't
loading cpufreq correctly. Ben's patch should fix it for all the 7447A macs
out there at the moment, and hopefully any new 7447A macs which come out in
the future.

Of course now that we are future-proofed against this, the next lot of
powerbooks will probably have 7448 CPUs, and so will need another patch. :S
