Problems with wpa_supplicant and Linksys WPC54G + WPA EAP-TTLS

I'm having trouble making my Linksys WPC54G (v1) card work with WPA
(EAP-TTLS) in Linux.
Basically, I can make the card talk to a WPA-PSK access point in Linux
with no problems, it's only when I try WPA EAP+TTLS that I fail. I know
the EAP+TTLS access point is configured correctly because I can connect
to it with a Windows machine and also a Mac.
The problem is simply not being able to authenticate to my access point
set up with WPA using EAP-TTLS. I've tried it against a Cisco Aironet
1200 and an Apple Airport Extreme. Both APs I can successfully connect
to with eap-ttls under Windows and MacOS.
In addition to not being able to authenticate, my machine
freezes/crashes sporadically when running wpa_supplicant.
I'm not sure if this is a wpa_supplicant or a ndiswrapper problem...
I'm very interested in any tips you may have. I'm sitting about 10 feet
away from the access point so I don't think it's a range problem.
Kernel "2.6.9-1.681_FC3.stk16" on Fedora Core 3 running on a Dell
Latitude D600 laptop. I'm using a 16k stack kernel.
In addition to the below, I've also tried the latest cvs versions of
ndiswrapper and wpa_supplicant without success.
I'm using ndiswrapper-0.12 with the bcmwl5a driver referenced for this
card on the ndiswrapper Windows drivers page.
I'm using wpa_supplicant 0.3.1. My .config for wpa_supplicant looks
like this:
CONFIG_DRIVER_NDISWRAPPER=y
CONFIG_EAP_TTLS=y
CONFIG_EAP_TLS=y
When I 'modprobe ndiswrapper', this shows up in dmesg:
ndiswrapper: using irq 11
divert: allocating divert_blk for wlan0
wlan0: ndiswrapper ethernet device 00:0c:41:2c:25:5d using driver
bcmwl5a
wlan0: encryption modes supported: WEP, WPA with TKIP, WPA with AES/CCMP
ndiswrapper: driver bcmwl5a (Broadcom,04/09/2004, 3.40.69.0) added
iwconfig shows wlan0.
The wpa_supplicant command I'm using is this:
wpa_supplicant -i wlan0 -dd -c /etc/wpa_supplicant.conf
My /etc/wpa_supplicant.conf file looks like this:
#ctrl_interface=/var/run/wpa_supplicant
#ctrl_interface_group=0
ap_scan=1

}
The output of wpa_supplicant is at the bottom of this post.
