Restricted mode not working with MA101, kernel 2.6.5, driver 0.12 from cvs

Hi,

for upgrading my kernel to 2.6.5 I got the latest drivers from cvs. With my old configuration from the 0.11 driver it was not possible to connect to the AP. 

The system log shows that the devices is registered correctly:

The device is configured like this:

Enabling the debugging showed that the card tries to connect but is not successful:

I rechecked everything and changed the security mode from "restricted" to "open" and the card works now perfectly. With the old 0.11 driver "restricted" worked without problems. Is this a bug? My access point is configured for restricted connections (it is a Cisco 1100).
It took me several hours to get my internet connecting working with this problem and I want to say thank you very much for the great support manual on the website and of course for the driver.
