hmm ... I wonder if I did something wrong or it has changed recently. Now my
USB stick appears as removable device but I definitely remember that under
2.4 (do not rememeber exact version) I tested it and it was never remounted.

it is not a bug it is by design :) In 2.4 kernel keeps track of USB UUIDs and
reserves once allocated host number in case you insert it again so it gets
the same device. So it is not a bug it is a feature :)
2.6 drops it completely in favor of user-level tools that currently do not
seem to exist (in a form suitable for deployment in real world that is).
