For the record, upgrading module-init-tools from 3.0-pre9-1 to
3.0-pre10-1  did the trick for me!

I do not know why this worked, because the changelog indicates only some
upstream release issue.

Also, as a loadable module (regardless kernel 2.4.25 or 2.6.3), `st' is
_not_ loaded (e.g., lsmod) until userland tries to use it.  In my case,
that is the `mt-st' package, which I have not changed in many weeks.

Bottomline, I upgraded module-init-tools and rebooted, and now userland
has no problems communicating with /dev/nst0.

Thank you for your help.
