can't be done, on recent releases.  well, at least for 1.5 and later
laptops.  it may still be operational for XO-1 [1].  our rfkill-based
mechanism was messy, and it was rejected when we attempted to put it

the mechanism hasn't yet been replaced -- someday the card should
power down with "ifconfig eth0 down". 


[1] on XO-1 the commands to try are "rfkill block wifi" and "rfkill
unblock wifi".
