There now seems to be certain time lag between tun module is loaded
and /dev/net/tun is created. So the script would die on the following lines:
modprobe tun
if [ ! -c /dev/net/tun ]; then
echo "/dev/net/tun doesn't exist"
exit
fi
Adding tun to /etc/modules.autoload.d/kernel-2.6 helps
but the question now is if it's normal behaviour or a bug
introduced with recent udev upgrade?

Yep. It's async and that's an expected udev behaviour.
I've been just lucky.
Those interested may search for "udev is too slow creating devices"
thread in linux kernel mailing list archives or google:)
