Uh. Did you try with a build from the netbsd-2 branch? From where I 
stand there is no good reason to stick with netbsd-2-0 unless you're 
in a production environment, since it sees almost no bug fixes.

Actually, some instance of hotplugd is sorely missing from NetBSD. 
Probably the most frequent complaint from students ("...sooo much 
easier on Windows!") using our lab machines concerns mass media 
handling (USB memory sticks, floppies).

How about pkg'ing the program and putting it on pkgsrc-wip?
