Mark,
Ive been using xorp on linux with vlans/multicast for a while.
(Im not running the "current" .ct branch, but one that
is close)
I have found that to make it work you need to treat the
vlan interfaces as separate interfaces not separate vif's
of a single interface. I actually bring up the interfaces
outside of xorp, but use xorp vif's that correspond.

My interfaces look like:
