Well, if you're willing to sink some time into it, you can try to
follow the ADSL bandwidth shaper howto:

(Gentoo version: http://gentoo-wiki.com/HOWTO_Packet_Shaping)

Unfortunately it's probbaly hard to do if you're running an exit node
and there are lots of exit ports, unless you have spare IPs and can
use one for the Tor node and one for normal traffic. This is what I
do. My script based on this howto is attached. It works EXTREMELY well
(Tor load has NO effect on normal traffic. I don't rely on
BandwidthRate/BandwidthBurst at all). 

The key property is that you cap your total bandwith through the box
(via the shaper) to be slightly lower than your link bandwidth so that
your box controls the queue size and thus ordering, not your uplink

I haven't posted my script anywhere cause I figured that having a
spare IP for your Tor node is probably pretty rare. However if you are
not an exit and thus only have one port for Tor traffic, it should be
readily adaptable based on port instead of IP.
