So, is the BIOS handover to the USB stack a prerequisite when resuming from

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.

In other words, do we need to implement BIOS handover before we can use
wake on usb keyboard input?

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

Or is there a workaround for this specific functionality?

Maybe check what Linux is doing.
