I had this work, once, using pepper's instructions. Then I restarted my XMing session to switch from Window to Fullscreen, and never got it working again (without changing anything, going through all the restart/reboot/etc hoops).
So I did a clean install on a virtual machine, with Lucid 10.4 rc, repeated pepper's steps, got the chooser to come up, closed down the x server, restarted, and same thing. So I rolled the virtual machine back, repeated pepper's steps, and it worked. Closed the x server, restarted, same thing.
I don't know why it works that first time - but the problem appears to be that GDM is only listening on the udpv6 port:
