Comment:
While I'm sure the patch makes it work again, I'm not certain it's the
right solution.  I expect it uses num_possible_cpus() instead of
num_present_cpsu() intentionally to prevent the module from being loaded
and then later another processor is hotplugged.  I would think the
correct fix is to make num_possible_cpus() actually return 1 on systems
like ours.

(Of course, I'm not a kernel developer and especially have little
experience with modern power management except as a user, so I could be
completely off on this one.)
