We've discussed why using uevents for this is not a good idea in the
past, and I don't think anything has changed since then.  You might want
to search the archives for details if you are curious.

As to other solutions, there's always netlink, and people have proposed,
seriously, to put dbus in the kernel to allow it to emit messages that
way.  I don't object to that, and I think there was even some patches
floating around to do that as well.  You might want to revive them and
see if that would fit your requirement here.

hope this helps,
