Right now, channel bandwidth is applied via debugfs - bypassing mac80211/cfg80211 entirely - so anything in mac80211 or above will think that it's still running in 20 MHz, whereas the driver is using 5 MHz. The main reason for this is that the 5/10 MHz support code in mac80211 currently disables 802.11n and changes the rate calculation, which breaks compatibility with other 5/10 MHz implementations.
