Indeed it is:
http://cgit.freedesktop.org/systemd/systemd/commit?id=bf7f800f2b3e93ccd1229d4717166f3a4d3af72f
I can confirm that this solved my issue. Toralf, please give it a try.
If you don't want to touch udev rules files under /lib or /usr/lib, you
can copy 80-drivers.rules to /etc/udev/rules.d and edit it there.
I'll try to get this change integrated into openSUSE 12.3.
Thanks,
