I am probably doing something wrong.  I have the same problem with both
the F3507g and the H5321gw: No RAs, no DHCPv6, and AT*E2IPCFG only
gives a LL address (only on the H5321gw of course - the F3507g doesn't
support this command as you noted).  And I cannot find any way to use
this LL address.

I observed one very strange thing on the F3507g: It sends gratious ARPs
for an IPv4 LL address when an IPV6 PDP type connection is established.
That was a bit surprising.
