I am afraid I spoke too soon - behaviour seems to be a bit random.

So, my dnsmasq configuration is available at
http://svn.cmeerw.net/cfg/fruity.cmeerw.net/etc/dnsmasq.conf

What seems to be happening is that only sometimes the statically
configured IPv6 is returned to that client (in addition to a dynamic
one). Sometimes (just after startup), only the statically configured
IPv6 address is returned to that client.

no ::13 this time, but later:

Any ideas?
