Thank you Will and Jacco -- actually the CentOS hint was what I needed 
-- I downloaded the 2.6.25 source (Karmic had 2.6.22) and compiled it -- 
and it works perfectly.

Problem I have now is that when I disconnect the VPN on the handset, the 
channel isn't killed. xl2tpd seems to close the tunnel, but the ipsec 
channel stays open. Then when I reconnect I get a "cannot install eroute 
-- it is in use for xx.xx.xx.xx". If I restart the ipsec daemon then it 
works again.

Any hints for closing the channel, or reusing the existing channel? 
Right now I've put a hack into /etc/ppp/ip-down to restart ipsec, but 
that obviously won't work for more than one user.

Thanks once again. After days trying, I can't believe I've got this far. 
Next step will be moving to private keys with any luck.
