I'm running a dedicated FE machine this way.  Right after kernel-2.6.32
it became necessary to do extra tweaks in the /sys tree to tell the
proper USB stuff to stay awake while the system slept.  Simply setting
stuff in /proc/acpi/wake no longer works.  Apparently I have one of
lucky motherboards.  Incidentally, there wasn't much documentation, nor
was it readily available about the post-2.6.32 /sys tweaks to support
USB wakeup from the mceusb receiver.  That system is sleeping now, but
if anyone needs the info, I can grab it next time it's awake.
