The problem here is that ipw2200 doesn't use the (new) the regulatory
domain configuration via cfg80211 and presents as a wired-style
interface.

"Upon the initialization of the wireless core (cfg80211) a world
regulatory domain (highly restrictive) will be set as the central
regulatory domain. If CRDA is present the latest dynamic world
regulatory domain is queried from CRDA; if it is not then a statically
defined list is used. 

When a wiphy is registered to cfg80211 (possibly via mac80211) the
effective set of permitted channels/maximum power is calculated for that
device based on the current regulatory domain. As initially that will be
the world regulatory domain, devices start out being restricted to
that."
