I will need to patch my kernel (obsd 3.2, sparc) as I cannot upgrade
due to hardware constraints and the mix of inhouse applications
that depend on that kernel.  I have been searching the net for the
old patches that were available for *BSD back in 2001-2002 but all
of the links are dead.  Do you still have any of that?  I could get
some hints from that code since I don't believe anyone patched OpenBSD
until 3.7 (very much later) and then all of the NetBSD, OpenBSD and
FreeBSD releases also incorporated a lot of bandwidth metering code
and other changes that make discerning just the PIM patches more
difficult.

Also, I fear that I cannot build xorp on my platform (it just doesn't
have the horsepower) so I will need to get by with 'pimd' or 'pimdd'
with PIM-SM support unless there is someway to generate a lightweight
version of xorp using a cross-toolchain somehow.

Regards,

Michael
