Possibly that such a GTK application could obtain that information via
hald(8) and dbus, but I honestly don't know if hald on NetBSD really
broadcasts the events you need, or if NetBSD itself provides a means
for hald to obtain these other than via dmesg(8).
I see no device event in kqueue(2), drvctl(4) is undocumented so source
would have to be looked at to know if it can provide live updates
(used by drvctl(8) currently, yet "strings /usr/pkg/sbin/hald | grep
drvctl" shows matches. I have no experience with hald however, never
having enabled that daemon on my systems)...
