I thought radvd can announce the prefix with the SLAAC bit cleared?
The currently (deployed) IPv6 model is that you MUST have an RA that
delivers the default router and locally attached prefix information.
So working out how to get radvd to emit what you want is the key.
Note however that at least dhclient, and one or two others, DHCPv6
software will presume a /64 prefix for any offered addresses, in order
to work around a bug-in-the-protocol where an RA failure leads to the
addressed clients being unable to speak to each other.

There's currently a default gateway and prefix option draft before the
DHC WG, which will help us resolve the above bug-in-the-protocol and
eliminate the strict requirement for RA.
