IPW2200 install

[marc <gmane@auxbuss.com>]

I'm running stable, except for a custom 2.6.12 kernel; if custom it can 
be called with a one-line fix in one of the .h files! Anyway, I'm trying 
to install ipw2200.

I installed the ipw2200 firmware via the ipw2200-firmware package, and 
the modules via ipw2200-modules-2.6.8-2-686 hoping that this would work, 
but the package installs files in /lib/modules/2.6.8-2-686, so it seemed 
unlikely. I considered copying the /lib/modules/2.6.8-2-686/drivers to 
/lib/modules/2.6.12, but somehow I didn't think that it would work.

So, I scouted around for the Debian way with the new kernel and found 
the following:

# apt-get update
# apt-get install module-assistant
# m-a -t update
# m-a -t -f get ipw2200
# m-a -t build ipw2200
# m-a -t install ipw2200
Thereafter, install the firmware from 

In addition to this, I installed build-essential, and did
# m-a prepare
before # m-a -t update

All went well until the build, which failed, as follows:

# Build the module

I found this: http://bughost.org/bugzilla/show_bug.cgi?id=702, which 
seems to be relevant. But how does one apply the patches?

Am I on the right track here?
