> x86, tsc: Fix a preemption leak in restore_sched_clock_state()

running 2.6.36-rc3-00464-g84e1d83 now, which includes that fix.

So far no resume issues, but the backlight does not power on again,
if the lid is opened.

Manually triggering display backlight increase (via fn-home)
changes it to 100% though.

I've not seen that behaviour for a very long time and never on the
X201. It has been an issue on the X200, which means probably around
2.6.30.

Cheers,

Nico
