Niels,
According to following URL what you are saying is not configurable:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat5000/rel_6_2/_con
fig/channel.htm#23937

"EtherChannel distributes frames across the links in a channel based on
the low-order bits of the source and destination Media Access Control
(MAC) addresses of each frame. The frame distribution method is not
configurable."

It is possible, however, to manipulate MAC addresses.
