You also need to have a 2.6 kernel............here is my custom kernel config for my Inspirion 600m.

what is custum with it?

Just about any kernel you config yourself is 'custom' . It generally means that stuff that the hardware/software needs is in there, and any extra 'fluff' is not. The advice is to use any config as a starting point, but change it to suit your needs.

For example: One of my networks is a gigabit network, so my controllers on them are all 1000's. So I make sure in the kernels on them that they don't have 10 or 100 or wireless. My notebook, on the other hand, only has a 10/100 ethernet controller, and the hardware doesn't change, so I got rid of all the non-intel and nvidia,etc stuff in there.

Hope that makes it a little clearer....lol

I have also write some short documentation about how to install and upgrade the IPW2200 driver on Slackware : http://www.informatix.or.id/willy/ac...o-on-linux.php and also http://www.informatix.or.id/willy/up...ino-driver.php
