netbsd 5.1/amd46 on Lenovo t410s

[sake <admin%saketec.com@localhost>]

hello,

I've installed netbsd 5.1 onto a Lenovo T410s. It seems to work fine
but the wifi card isn't found by the system.
The card is an Intel Centrino Ultimate-N 6300 which (I think) is
supported by the iwn network driver which is already in the GENERIC
kernel. dmesg shows an entry for a network card "not configured"

So how do I get netbsd to configure the card an make it usable?

thanks in advance
sake.

P.S. I wrote this already to netbsd-users but didn't got an anwser there.
