i have a generic hot plug/event notification in mind.
i have a semi-working prototype, hope to get it done sometime around easter.
this will leave enough time to convert usbd and pccardd to use it.
maybe this will even let enough time to start my devd (a daemon that creates
device node, when needed). well, just dreaming i guess.
