Sure.  Here's a diff and a brief explanation.

I added the WPA and WPADRIVER variables to my ifcfg script (eth1 in my
case) and created a proper wpa_supplicant config file.  A basic config
looks something like this:

# allow frontend (e.g., wpa_cli) to be used by all users in 'wheel' group
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
#ap_scan=2
#
# home network
network={
     ssid="YOURNET"
     scan_ssid=1
     key_mgmt=WPA-PSK
     pairwise=TKIP
     group=TKIP
     psk="super-secret-passphrase"
}

I had created the ifcfg-eth1 file using system-config-network while
trying to see if it would support wpa, so all I had to do was tweak a
few things by hand afterward.

HTH,
