Custom kernel question

[John Ruschmeyer]

For a while, I've been building a custom kernel for my system based on 
the linux-source package with the addition of the patches for Win4Lin 9x 
support (mki-adapter). Using kernelpackage, I can build an installable 
kernel and headers which work fine on my desktop system (very mundane 
hardware).

For my laptop, though, I also need the madwifi driver which is part of 
the linux-restricted-modules package and is not part of my custom kernel.

So, my question is how can I set up a custom kernel which includes a 
corresponding linux-restrictred-modules?

Thanks...
