You don't need a patch at all.  What you do is:  Queue on the physical 
interface, classify on the vlan interface.  It is broken to allow ALTQ on 
a virtual interface if you can do it otherwise.

in pf.conf speak:

If you have "ifconfig vlanX vlandev bge0 ..."

altq on bge0 .... queue { vlan0, vlan1, ... }
queue vlan0 ... { vlan0_foo, vlan0_bar, ... }
queue  vlan0_foo
queue  vlan0_bar
...

pass on vlanX  ... queue vlanX_foobar

And there you go.  No patch - whatsoever - required here.
