OK, so at the moment both are not installed, but their configuration
files are still present. The last versions that were installed
correspond to the old "matching pair" from Sarge. These were probably
removed because of dependency conflicts during the upgrade. udev was
most likely not replaced because the Etch version needs a newer kernel
(2.6.12 or higher). I guess the best thing to do is to install the
appropriate linux-image-2.6.15, boot into it and then reinstall udev.
(I am not 100% sure here, it might also be possible to reinstall udev
before booting into the new kernel.) You will probably see a message
which asks you to purge the hotplug configuration scripts. After you do
so, run "udevsynthesize" as root and I would hope that then your
/dev/input/mouse.. devices will work normally again.
