11RC4 and WiFi issues - wpa_supplicant issues ioctl's with invalid argument

Hi all!

I decided to install 11RC4 on my HP 620 laptop. It mostly seems to work 
in the first day of use, but I couldn't get wireless to work with 
wpa_supplicant (my configurations files are the same as before).

I launch wpa_supplicant and get an error. Scanning works. Sometimes at 
least.

WiFi card is:
disc$ dmesg | grep ral0

(interesting is the single timestamp out of line)

scanning did work yesterday, but not today as I am trying to write this 
mail :)
disc$ sudo ifconfig ral0 list scan
ifconfig: The interface must be up before scanning.
disc$ sudo ifconfig ral0 up
disc$ sudo ifconfig ral0 list scan
<empty>

What worries me is this though:
disc$ sudo wpa_supplicant -Dbsd -iral0 -c /etc/wpa_supplicant.conf
Successfully initialized wpa_supplicant
ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Invalid argument

<crl-c>
^Cral0: CTRL-EVENT-DSCP-POLICY clear_all
ral0: CTRL-EVENT-DSCP-POLICY clear_all
ral0: CTRL-EVENT-TERMINATING

dmesg shows no further errors!

However, now, I can run list scan and see networks

  sudo ifconfig ral0 list scan

I did hide the SSID's and BSSID's for this mail, but they look correct.
