Is there any way to temporarily spoof the MAC address on the Touchpad?

I tried;

ip link set address xx:xx:xx:xx:xx:xx dev eth0

and

ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx

And just received "RTNETLINK answers: Operation not supported" and "ifconfig: bad address 'hw'" respectively.

I'm using the F4 kernel currently. Does the kernel/wireless hardware support doing this?
