This is by design -- if the card has a regulatory domain set
programmed into it, you won't be able to override it. So its not
that its failing its more that the card already has its regulatory
information properly programmed. This goes for Intel and Atheros wireless
cards. Cards that have no regulatory implementations though can benefit
from user input as there is none -- that accounts for the rest of the cards.
