Like I already said: Hotplug worked on this machine and the working of
hotplug is reproducable and the not working of udev is also
reproducable (a simple chance with aptitude install udev or aptitude
install hotplug).

This is the most recent etch kernel, but I tried Linux 2.6.14-2-k7
from SID, but then I got this dmesg output:
----------------------------------------------------------
lp0: using parport0 (interrupt-driven).
