  Log:
  Minor tweaks to the resume code that might help people debug.
  
  * Add hw.acpi.resume_beep tunable and sysctl, default to 0.  Beeps the PC
  speaker soon after waking to diagnose whether the wakeup code is even
  getting run before other drivers possibly hang the system.  To stop the beep,
  cause another beep (i.e. keyboard bell).  Submitted by takawata@, I changed
  the frequency to be lower.
  
  * Use 4096 instead of 4 byte alignment.  Might be useful although doesn't
  seem to be necessary.
  
  * Remove a useless assignment to acpi_reset_video.  It was overwritten by
  the default sysctl value anyway.
