ok. You should follow the steps here
http://easyurpmi.zarb.org/
but i realize that that probably won't work if you don't have net access in linux.
the RPM is located on disc 3 with the filename, kernel-source-2.6-2.6.11-6mdk(i forgot the rest).rpm just look for that and install it.
you must uninstall the stripped version first too.
