Richard hasn't touched it for about a year and since then only bugfixes and
my changes to the kernel interface went in.  No one has stepped up to
maintain it and with udev we have a proper replacement now.

I will do some more work before 2.6 (mainly trying to implement Al's
refcounting scheme to avoid stale entries), but that's it.
