Hello Frans,
I found that once installed the udev report is different (but udev
0.105-4 should be the same, or not?):
$ uname -a
Linux debian 2.6.18-4-686 #1 SMP Mon Mar 26 17:17:36 UTC 2007 i686 GNU/Linux

And the device /dev/cdrom exsist.

Yes, using the etch netinstall

# udevinfo -a -p /sys/block/sr0

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
