If you do not stick to the "standard" configuration via rc.conf, one
possible workaround is:

- send a router solicitation and get a prefix via router
  advertisements
- somehow (e.g., by a shell/perl script) identify the prefix
- assuming the prefix is "P/64", do the followings:
  # ifconfig IFNAME inet6 P::1 prefixlen 64 alias autoconf
  # ifconfig IFNAME inet6 P::2 prefixlen 64 alias autoconf
  # ifconfig IFNAME inet6 P::3 prefixlen 64 alias autoconf
  ...

The keyword "autoconf" is the point.  It tells the kernel that the
addresses should be updated based on succeeding router advertisements.

(This may not work depending on the FreeBSD version.  I've tested the
procedure on a 5.3R box)
