Under Linux, the command is "ifconfig ethXX hw ether xx:xx:xx:xx:xx:xx".

However that won't work with any released version of the orinoco
driver, including 0.11b.  It's trivial to implement, but I basically
just forgot to do it.  The code to do this is in the "testing"
version, but the testing version is badly broken at the moment for
other reasons (we're completely reworking the locking structure).
