On a related note, if your board supports wake on USB then the USB-UIRT
receiver/blaster might help. Using a windows binary you can program it with
up to 4 codes that it will respond to and wake up the box with. Obviously
you MB needs to support wake on USB and keep the USB powered appropriately.
Check out the USB-UIRT forums for more info.

Cheers
