Differentiated Service on Linux HOWTO (work in progress) could be of some 
help for you.

Have a look at http://opalsoft.net/qos

[Burnside, Andrew]

Having had another look at the kernel, and at the lartc howto it seems that
tc filter when policing may be able to reclassify out of profile traffic to
BE, but no more than this, without first putting traffic into a queue.
