wpa_supplicant / ndiswrapper / Dell WLAN 1450 / Slackware issues

[Philip H. Schlesinger]

Going nuts here. I'm a semi-newbie to Linux. Configuration:

Laptop:
Dell Inspiron 600m
Dell Wireless 1450 a/b/g card
Dual boot to: Slackware 10 (fully patched to current via swaret and 
kernel 2.6.9) and Windows XP
NDISWrapper 0.11 because the 1450 is Broadcomm based (booo!!!!!!!!!)
WPA_supplicant 0.3.2 (tried 0.3.1 & 0.2.5 also with no luck)

Network:
D-Link DI-614+ (patched to firmware 3.43)
hidden ssid
set to WPA-PSK

The D-Link connects fine when in Windows. If I try to connect in 
Slackware to a non-encrypted WLAN (not my own, but for instance in a 
coffee shop), NDISWrapper works fine.

wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
#
# home network; allow all valid ciphers
network={
ssid="ssid is entered here (not going to reveal it)"
scan_ssid=0
#ap_scan=2
key_mgmt=WPA-PSK
psk="key is entered here (not going to reveal it)"
}
#

Note, by the way, that the ap_scan line, while I'd like to use it, 
doesn't work - I get "Line 8: unknown network field 'ap_scan') (this is 
PROBLEM 1)

Here's what happens with the ap_scan line commented out:

bash-3.00# wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -dd
Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver 
'default'

removed it)

Ideas? The ap_scan line should work - it doesn't. The program doesn't 
like the first two lines of the conf file either...Help!
