tun device on 2.6?

[Bradley Alexander <storm@tux.org>]

I have just built a Sparc Ultra 2 with unstable and a locally compiled
2.6.3 kernel. I am trying to run openvpn, which requires use of the tun
device. I set up /dev/net/tun as noted in the kernel documentation, but
when I try to bring the device up by hand, I get 

[root@neghvar net]# ifconfig tun0 up
tun0: ERROR while getting interface flags: No such device

When I boot 2.4.24, the device works fine. Am I missing some software that
2.6 requires or is it broken? I searched on google for anything regarding
this issue, but the only thing I found was a two-message thread on the
kernel list saying "tun is broken on 2.6.3" and "no its not, I'm using it"
with very few details. Any suggestions?

Thanks,
