Seems logical to me.  Though I guess it doesn't make much difference.

I'm not a real expert on the APM spec, but I do know that whatever apmsleep
is going with the RTC definitely works on my laptop and my ATX desktop, so
the extra APM features may not be necessary.  But hey, try it if you like.

Anything that helps integrate apmsleep support into cron/at (in a non-ugly
sort of way) would really be great.  I've been hoping for such a thing to
come and hit me in the head, but I don't have time to write it.  And Peter
the apmsleep guy says there may already be "laptop cron" programs around
that do what I want -- though I haven't personally seen any (anacron, aka
running my nightly events at the least convenient time possible, is not the
answer I want).

If you write it well and it looks like it belongs, I'll be happy to merge
changes into the apmd package.

Have fun,

Avery
