Theoretically this particular system will do suspend to ram, and at some
point I'd really like to have that.  But from what I can tell, the USB
1.1 device can only wake a system from hibernation, and the USB 2.0
device can only wake it from suspend-to-ram.  My imon hooks in as a USB
1.1 device, and none of the dirty tricks I've tried, like blacklisting
OHCI to force EHCI to grab the device have worked.

Also on that topic, obviously the 5VSB supply goes the the imon, which
is why it can stay on when everything else is off.  I would think that
that's so that you can turn the thing on with a remote.  However I
haven't been able to do that.  Will the imon only turn it on with an
imon remote?  I have an rc6 remote that fails to turn it on.  This is
probably better for the LIRC list.  I just joined, and need to lurk
there for a little longer before posting.
