It may be possible to unplug the DSL modem's power cord and replug it in; it could be the most recent MAC address is always stored in memory, and the modem can't differentiate between a second computer and a replacement computer. If it is stored in the DSL modem, powering it down should make it "lose track" of the MAC address and take the new one. If it's stored on the DSL provider's system, you can probably call the DSL provider (may be a hassle explaining this) or do some of the changes others have suggested to change the apparent MAC.
