Sorry for coming late to the party ... the current code works nicely on
the 17" PB. On the first boot with that code, I had the PLL freak out (or
so it looked like) but I couldn't reproduce that. Needless to say, the
new PLL fixup code produces the same dividers as the hardcoded fixup
before, so it should work :-)
