As I said my question might have been naive - never played with IPv6
before. What you describe is exactly what happens here, the missing point
is that I did not run RIPng yet.

The interfaces come up like this:

pppoe1: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1492
        inet X.X.X.X -> Y.Y.Y.Y netmask 0xff000000
        inet6 fe80::a00:20ff:fe99:fc91%pppoe1 ->  prefixlen 64 scopeid 0xb

The first confusing point is that this gives no hint wether IPCP6 succeeded
or not (it did, I checked via the debug log); with a INET6 enabled kernel all
pppoe interface look like this, even those to providers that do not support
v6.

Will /etc/rc.d automatically run RIPng for me if I configure ip6mode to router?

Yes.

Thanks,
