Hi,

I'm not sure. You'll have to find out. It is what happens when you 
suspend which decides if you get the resume event or not. Once resumed 
the system will manage somehow, either full reset or handover.

Might depend on the BIOS make. I've never tested this on FreeBSD before 
so I don't know.

Maybe check what Linux is doing.
