The message itself means that according to the driver we get a transmit 
packet that exceeds the WMM txop. This message itself does not prevent 
the packet from being transmitted. I have not seen the message lately in 
recent driver versions.

You can either try compat-wireless (see [1]), which should support 
2.6.32. Or you can try the latest 3.3 kernel.

btw. 9 out of 10 times not getting an IP with dhclient means a problem 
with security credentials/handshake/etc. So if the option above do not 
solve your problems, we have to dive into that.
