Jeff, I think this should be merged into 2.6.29 unless Linus still
objects.  Linus, as discussed in this thread, this is workaround for a
hardware / firmware problem and vanilla windows also suffers the
problem, so as ugly as it is, we need this to prevent double spin down
on the machine.

Thanks and happy new year.
