Ermm, ar9170 never supported AP mode and carl9170 only
allows the most basic implementation.

WEXT?
the README has a "SYSTEM REQUIREMENTS" section:

no word about carl9170 Version?
The latest carl9170 1.0.1.1 (together with hostap_0_7_1 and 2.6.33-rc6-wl)
should produce something like:
Configuration file: /etc/hostapd/hostapd-test-11g.conf

BTW: Neither carl9170, nor ar9170 support the crypto engine when AP/IBSS
is enabled. If you have a weak CPU (e.g.: ARM Atmel at91SAM9263 200mhz),
you should run openssl's algo benchmark to determine if the system can
actually handle WPA without dropping/delaying too many packages under
pressure.
