Adding a ::/0 route doesn't work:

connect: Network is unreachable

A route assigned by addrconf works.

Reverting this patch from 2.6.22-rc3 fixes it:

	    [IPV6]: Fix routing round-robin locking.

This patch is was added to 2.6.20.5, breaking -stable too.

Rather than reverting that patch, applying this patch should fix
your ipv6 issue:

I'll wait for Dave or Yoshifuji to decide if this is a proper -stable
patch.
