Firstly, you need a motherboard that is able to power the
USB ports from +5vsb - The standby line. Quite a few are -
Check your manual.
Then you need to do the following (or similar) in one of
your startup scripts:
echo USB1 >/proc/acpi/wakeup
This sets the ACPI subsystem so it's expecting wakeups from
USB1 - You may need another number.
Then I put the PC into standby - In reality it's a bit more
complex than this, but it starts like:
echo mem >/sys/power/state
Then you *should* be able to power back on with your remote.
Various things may make it more complex - X may need stopped
before suspend and restarted afterwards, etc. Some drivers
don't handle suspend too well at all.
I'd really suggest STR rather than Hibernate - It's so much
faster to resume and the difference in power consumption
isn't too bad.
