You sound very confused.

Multicast has been a non-optional part of NetBSD for a few
months now. It should just work for you. Please tell someone if
it doesn't.
Hang on. You still need to say options MULTICAST MROUTING in the config
file surely....
No. `options MULTICAST' is defunct. `options MROUTING' is still
needed for multicast routing.
Also, getting a multicast kernel to enable promiscuous mode can be
a pain, [...]
Huh? If promiscuous mode (used by BPF) and multicast don't work
together, it's a bug and should be reported. But I should add that
this has been tested is most of the ethernet drivers and is known to
work.

What *are* you talking about? For starters, 0.9 doesn't have
multicast at all.
Oh yes. one last thing. NetBSD current has adopted new setsockopt()
flag values which make running the binary-only code (vat, sd) very
hard.
For a while, the multicast options were overlayed on some old
IP_OPTIONS* and the old constants were changed (per the original
multicast code that we incorporated). This was, however, reversed.
The current values were decided upon mutually by NetBSD, BSDI, and
4.4BSD-Lite, as I recall, to preserve compatibility with old
executables.
