Dear list,
thank you for the answers. New question for problem at the very end.

I think it rebuilded the modules because I did delete the deb file
in /usr/src/ . Anyway tried this again, but to no avail. Just for
reference.
$ sudo aptitude remove --purge madwifi-source madwifi-tools madwifi-modules-2.6.26-1-686
$ sudo rm /var/cache/apt/archives/madwifi-*
$ sudo rm /usr/src/madwifi-modules-2.6.26-1-686_0.9.4+r3772.20080716-1+2.6.26-4_i386.deb

Well it did not.

I set it to 2 and 5 and it did not help.

What still bugged me was the message

even before the sleep command in the script. Therefore I tried
$ LANG=C dpkg -l udev

$ sudo aptitude reinstall udev
but with no luck. Then I decided to stop the daemon
$ sudo invoke-rc.d udev stop

and it WORKED ;).

So for me it looks like udev is the culprit. Any ideas how to fix this
or where this renaming stuff is located?
Thanks in advance. Bests,
