It's not sufficent for a manufacture of RF equipment to say "don't do
that".  They have to take real, more or less working steps to keep you
from doing things you aren't supposed to do.  This is why the Linksys
link boosters were pulled.  FWIW, there is a solution to this which Sam
used to when implementing ath(4).  That is to implement a binary-only
hardware access layer, ath_hal(4), that keeps you from doing things you
aren't supposed to with the highly programable chips.
