Depending on your switch, e.g. will it spaz out or not, you can try to 
set the MAC address to be the same on both NICs using your OS.  Some 
switches, as I hinted on, will not like this at all... others understand 
it if they really support trunking.  Short of that it is just an 
annoyance in the logs for devices that keep ARP tables.  I guess you 
could always put a small router in place between the server with the 
trunked interfaces and m0n0 thus illiminating the SAP/ARP.  (If your 
switch has the ability you can do that on the switch too.)
