From what I see from the error, the module is probably there. Maybe you should try going to root first (using the su command, pressing return, then entering your root password - default password is root) then trying modprobe ipw2200 again.
Thanks for the answer. I solved the problem. Because of version "cooking" there was perhaps a change between "2.6.34" and "2.6.36". In the newer kernel i found all files and so i booted the new kernel. Now everything works. Very nice operation system, thanks.
