MAC reconfiguration issues

When I try to reconfigure my MAC address with

ifconfig eth0 hw ether [MAC] up

I get an error telling me that the device or service is busy. I
migrated over to Mandrake 9.2 from Redhat and never had this problem.
Can anyone help me resolve it?

I'm trying to connect to a university LAN and I have to change my MAC
address, as the card came from the factory straight zeros.

Then do it when it is not in use!

Take it down first. Remove the driver module (to make sure nobody is
using it!). Reload the driver. Set mac.

I've tried that. Ifconfig eth0 down, right?

Yes, then take out the driver module, reload it. Then set mac.
