This patch is wrong (i.e the code is fine as is).
By default there is a three band scheduler (pmap_mode=0). You can
over-ride it to have more bands by using the "priomap" construct
(pmap_mode=1).

Yes -- it can be done. Override the 3 bands to 4; attach TBF to the
classes you want; use ipchains to do the marking (at any spot where a
chain can be attached) and classify using the fw classifier on the
egress to direct packets to the appropriate class.
