Modifying the image file to accomodate ndiswrapper

How can I modify the koppix image file so that the ndiswrapper utility is included? I was hoping to use this to try and get my Broadcom 54g Maxperformance 802.11g wifi to work (I'm on an HP Pavilion zx5078cl) with the windows drivers that I've downloaded. Koppix works great on my laptop, all I need now is to get my wifi up. I'd like to avoid installing onto the HDD (I'm waiting for my friend to return my copy of Partition Magic 8 ) and would really enjoy keeping everything on just the one CD.
I've downloaded ISO buster but I'm assuming it can't read the EXT2 (or 3?) FS.
Anyone know anything that I could do to get this all set up?
I'm a pretty hardcore newbie at this, so breaking it down as much as possible would be very appreciated.
Thank you.
