You can assign a new mac address, with the following precaution: bit 46 must be 1 (this means: Locally administered) Burned in addresses come with bit 46 set to 0. (bit 46 is the second bit of the OUI section). I don't know if your system supports any way to modify mac addresses, but this subject has been discussed previously on this list, so a google search should give some positive results (there is a C program floating around that is reported to work on many cards).
