Serial port numbers changing at each boot

A machine with a Gigabyte g33 motherboard and two serial expansion
cards has an interesting situation in which on each boot the serial
ports get different tty numbers. Why should they change on each boot,
and how can I prevent that?

The machine is currently running Ubuntu 10.04. I had run various
Ubuntus and Debians without issue in the past. Thanks.
