I have just those rules. But what devices does it create in /dev?
I have /dev/ptmx and a directory /dev/pts (with nothing in it). The
directory is owned by root.root with access rights 755. This maybe the
problem - can you tell me what yours are.

udev is running
kernel is 2.6.20
(I would normally go to a console and do a uname -r for you - but I am
hobbled because I can only get to a console with CTL-ALT-F1, but then I
can only get back if I restart kdm - because a bug in the i810 driver
locks my machine solid if I try to come back via CTL-ALT-F7).
