as per your provided info, this indeed resemble to a udev related issue.
this is quite probably due to the upstart + sysV mix that is in use in
natty, with udev being an upstart job, while nut is still a sysV
(compatibility) one.
I've sadly not had time to install an actual natty, and pbuilder disable
udev.

the final solution will come with NUT conversion to upstart (I had a session
at the UDS today on that).
for the time being, you can try to up a bit more NUT's ranking by doing:
$ sudo mv /etc/rc2.d/S50nut /etc/rc2.d/s99nut

and check if the situation has improved.
I'll give a word tomorrow to upstart developers on this.

cheers,
Arnaud (from UDS Budapest)
