Yep, I found a number of them, but I promptly forgot them in excitement when I found the one I actually wanted. If you want to check them out yourself, they appear to congregate in the kernel tree at net/sched/sch_* [1].
The only other qdisc I have much experience with is sch_netem, which emulates behaviors of a WAN (delay, loss, etc). I used it in this post [2] to conduct adversarial testing of MySQL replication (search 'tc qdisc').
