Hmm.. I'm with Andrew on this one - I'd much rather really pass them to 
user space as strings. We already pass a number of strings as environment 
variables.

In fact, what's wrong with DEVPATH? Which we already expose as the
NAME=xxx environment variable. So if the kboject associated with a device
has has this string associated with its name (which it should), then 
hotplug will automatially pass that as the DEVPATH.

So if you just fill out the kobject name with the product ID's (well, 
with the proper escaping of strange characters, of course), everything 
should just work. No?
