trying to use SHA256 on hostapd

Hi all;

Using hostapd 0.6.8 with madwifi-0.9.4, linux kernel 2.6.18 (old but
works...), on an AR5212 802.11 b/g card,
using wpa-psk mode w/ccmp (aes), known as "WPA2"

in hostapd.conf using the line
wpa_key_mgmt=WPA-PSK      everything works


but trying to use SHA-256 like this
wpa_key_mgmt=WPA-PSK-SHA256       produces errors when I start hostap

Line xxx: invalid key_mgmt 'WPA-PSK-SHA256'
1 errors found in configuration file '/etc/hostapd.conf'

       [ !! ]

I get the exact same results (working and non-working) on other versions
of hostap.  Reading the sample config file does not clarify; how do I
enable this?

Thanks,
David
