With both of those patches applied my system has no problems associating and obtaining an IP address.  Before the patches were applied the system would time out  on the dhcp requests, and fail to obtain an IP due to it hadn't associated with an AP in time.

I was finally able to get connected to the schools WPA network with wpa_supplicant, by removing:

   ca_certs=""

from the configuration:

network={
        ssid="School_WPA"
        proto=WPA
        key_mgmt=WPA-EAP
        pairwise=TKIP
        group=TKIP
        eap=PEAP
        identity="me at school"
        password="password"
        phase1="include_tls_length=1"
        phase2="auth=MSCHAPV2"
}

found the problem by using wlandebug scan+assoc+auth, and saw it was failing when it tried to load the certificate file.

I also tested the ndis_scan10.diff  on my home and work networks and didn't have any problems assocating with the APs.  I did notice that 'ifconfig ndis0' on my home network would show the ssid, while the work and school network wouldn't show the connected ssid.

'ifconfig ndis0 scan ; ifconfig ndis0 list scan' still doesn't show the available APs.  But they still show up in wpa_cli when using scan_results.

I had created the following script for the testing:

---
#!/bin/sh
set -x
newsyslog -F
kldload bcmwl564_sys.ko
sysctl debug.ndis=1
wlandebug -i ndis0 scan
ifconfig ndis0 scan
ifconfig ndis0 list scan
kldunload bcmwl564_sys.ko
