* Actually call prepare_sleep_state() instead of calling enter_sleep_state()
  twice...
* Commented out disabling interrupts when calling enter_sleep_state(), as our
  ACPI modules would then crash (needs memory & uses sems with interrupts
  disabled). This way, it at least works on some hardware, including emulators
  (as before).
