> Log:
> Retire pmtimer driver. Move time fixing into apm driver. Move
> Iwasaki-san's copyright over. Remove FIXME code that couldn't possibly
> work. Call tc_settime() with our estimate of the delta we've been
> alseep (the one we print) to adjust the time. Not sure what to do
> about callouts, so keep the small #ifdef in place there.

RELNOTES: ?
Reason I ask is this effects custom kernel config file(s)
