Yes...  The point of radvd is to advertise the configuration of the link
to the hosts on the link, not to configure the router.

radvd only changes the prefixes it advertises when it receives a SIGHUP.
Thus, you must have a script set up that HUPs radvd when your dynamic IP
changes.  For example, if you use PPP (over dialup or DSL or whatever),
you could put a script in /etc/ppp/ip-up to send a HUP to radvd whenever
the PPP link came up and obtained a new dynamic IP address.  This script
would be the appropriate place to change the routing table and IPv6
address of the router.  -Nathan
