I came across this problem as I have been installing and configuring
debian on one box, then removing the hdd and putting it into the new
box which is not identical but similar enough.

Because the network cards were different though, there was no eth0 and
it took a good couple of hours to work out why I was suddenly missing
an eth0 when it was there a few minutes ago and the driver was loading.

Seeings udev is in /etc/init.d/udev - would it be possible to just
re-issue a /etc/init.d/udev restart?

I know this may possibly break things though... just a thought..
