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.
