Try looking at ALTQ, it can do what you describe. But last I check it still 
doesn't have a patch for FreeBSD 4.4, only patchset until 4.3 is available.

Not relevant to the question somehow...does anyone have any idea as to 
whether ALTQ will be integrated to the main FreeBSD tree? It will be nice to 
have this thing in the base distribution, and thus many more reason to use 
FreeBSD!!!
