Hehe, yeah, that is a problem. 300mbit in + 300mbit out requires a quality machine, probably with multiple PCI busses, or 64bit if possible. > Our ISP is probably interested..

Well, some things can be done at that rate and other things can't. 155Mbit/s is well within Linux' range, we've routed 90mbit/s (90 in, 90 out) on a low end machine. RED certainly works at those rates as it is very simpleminded. SFQ is probably out, unless you recompile your kernel. At those speeds you may want larger queues than 128 packets, which is the SFQ default. PRIO would also not be a problem. I think a PRIO with RED qdiscs may be what you want. And who knows, CBQ is also *very* lightweight in its determination of link utilization. I would say that this is most likely possible at 155Mbit/s. You will need to ask around - lots of people are doing gigabit experiments, some configurations work far better than others.
