I've tried this with 4.2-RELEASE on a single PIII-500 with 128 MB RAM and
2 fxp0 Interfaces. It was attached to a Nortel Baystack 450 running a 2
port "Multinlink Trunk" Configuration.

It worked absolutely flawlessly. 

When downloading a single 60MB file to 3 clients by FTP, it achieved
~21 MB/sek output (netstat -I fec0 -w10). I had to use 3 clients due to
lack of a second speedy client. 

I'm impressed. 

Am I right that a single transfer is always limited to the bandwidth of a
single interface? The above mentioned Switch and Linux ditribute traffic
in a round robbing manner. Both cooperate with Cisco's Etherchannel
(tested against a Catalyst 2924). How about adding a round robbing
distribution, too? This is epecially usefull for getting higher throughput
when traffic mostly takes place between 2 hosts.
