Since we (SUSE, many thanks to Andi Kleen and Andrea Arcangeli) have already fixed most of the breakage "usb-handoff" causes on certain (nvidia, etc) boxes, because of unusual memory layouts and iounmap() that can't cope with that, I believe it'd be a good idea to enable "usb-handoff" on vanilla kernels by default as well - SUSE already has it enabled for more than a year.
