I'm using 2.6.37 with the patch that I sent you in one of my firewalls:
$ uname -a
Linux debian2 2.6.37 #7 SMP Mon Feb 7 10:34:10 UTC 2011 x86_64 GNU/Linux
Everything works fine.

It's stable, I'll release 1.0 soon.
Some more work can be done on it to port it to libmnl, add H323 and SIP
support, active-active support, among tons of many other improvements.
But that can be done in the future.

As said, here works fine with the patch that I attached ;-)
