I'm working on the device registry patch (www.tjansen.de/devreg) that allows
you to retrieve the DevFS filename of a physical device. The next release
will be in a couple of days and adds a DEVICEID environment
variable to the hotplug invocation. You can use give this device id to
libdevreg (or lsdevreg in a shell script) to get the name of its device
nodes.
Note that devreg is experimental code and may be a dead end. I have not
got any reaction from Linus or other kernel hackers, so I don't know
whether it has a chance to be included in a official release. And even if
it does, it wont before 2.5.
