1. use openssl package to generate cross-compiled crypto libray libssl.a and libcrypto.a
2. Edit Makefile, change
gcc=powerpc-405-linux-gnu-gcc
LIBS += -lssl -lcrypto to LIBS += libssl.a libcrypto.a
3. Edit defconfig, comment/uncomment or add the follwoing lines
#CONFIG_DRIVER_HOSTAP=y
CONFIG_DRIVER_MADWIFI=y
CFLAGS += -I. # include current directory
4. copy defconfig .config
5. copy madwifi driver include directories: include and net80211 into current hostapd directories
mkdir net80211
mkdir include
cp ~/madwifi-ng-r3406-20080326/include/*.h include
cp ~/madwifi-ng-r3406-20080326/net80211/*.h net80211
6. copy ssl include directory into openssl directory
mkdir openssl
cp ~/openssl-0.9.8g/include/openssl/*.h openssl/.
7. run make

7. wlanconfig
Current Madwifi driver supports multiple APs and concurrent Ap/Station mode operation on the same device. Each instance of AP or station is called Virtual AP(VAP). VAPS share the same underlying phy layer, which is the base device (wifi0) when driver is loaded.
Creating or destroying VAPs are done wlanconfig
wlanconfig VAP create wlandev BaseDevice wlanmode mode [bssid] [-bssid] [nosbeacon]
wlanconfig VAP destroy
wlanconfig VAP list [active|ap|caps|chan|freq|keys|scan|sta|wme]
