I think this is a bug: There's a different code-path used to trigger 
periodic RAs when no DHCP is configured.

If I'm right, then

kill -ALRM <pid of dnsmasq> should start periodic RA's and configuring 
any DHCP service, IPv4 or IPv6 should also make things work.

Please let us know if this works, if it does I'll make a patch ASAP.
