I'd actually prefer for it to be some /sys interface or other. Maybe
it could even be per-device or class, and you could do something like

   echo "enable bind" > /sys/bus/serio/uevent

the uevent code already supports a per-node "filter" function, maybe
that notion could be extended to also have a filter for uevent types.

But I'm just handwaving. Maybe it's better per uevent socket or something.
