o Enable standby mode in apm utility. You need a newer kernel for this

  functionality to work (however, the kernel changes were committed
  to current at 1998/07/05 23:29:11 PDT).
o Enable setting of a timer for later wakeup.  Note, not all APM
  BIOSes support this for all modes (mine doesn't support waking up on
  a timer from standby mode).
o Print out the APM capabilities, as reported by the BIOS.
o Report wake on ring indication.  No way to enable/disable this, but
  it is reported.
o update man page with above
o The output of this command has changed, so if you have a script that
  parses its output, then you may need to rewrite it slightly.
o The code attempts to deal with older kernels than July 5, 1998, but
  that part of the code isn't well tested.
