After another re-install ascii and upgrade to beowulf to verify I can confirm that if you remove or rename /run/udev prior to the dist-upgrade the check gets disabled. It's pretty obvious in the pre-inst file, but as it only ever caught me in the middle of an upgrade when I was more interested in getting things running rather than finessing a work-around I never really looked too hard.

In my case I ran the dist-upgrade until it bombed out, rm -r /run/udev and then ran the upgrade again and this time it ran to completion.
A manual /etc/init.d/eudev restart afterwards re-created the directory and we are off to the races.

I can't see why I wouldn't just zap /run/udev before the upgrade.
