I have successfully remastered knoppix-5.1.1 by removing and adding packages.
I now would like to be able to activate my wireless adaptor, being an intel ipw3495 card.
Software and build instructions are available at e.g. http://ipw3495.sf.net, but
when these are executed, the system (knoppix) reports:

=========
ERROR: A compatible subsystem was not found in the following path[s]:

/lib/modules/2.6.19 /lib/modules/2.6.19/build

You need to install the ieee80211 subsystem from http://ieee80211.sf.net
and point this build to the location where you installed those sources, eg.:

% make IEEE80211_INC=/usr/src/ieee80211/

or use the 'make patch_kernel' within the ieee80211 subsystem to patch your
kernel sources.
===========

Let's try do that:
root@Knoppix:/tmp/ieee80211-1.2.16# make

make: *** [modules] Error 2
========

Is it possible to obtain the /lib/modules/2.6.19/build/ contents?
There does not seem to be a deb pkg around that provides this directory (debian provides
packages up to and including 2.6.18....

Are there packages with kernel headers (I think it is) around for knoppix' 2.6.19 kernel??
If not, is it possible to create them from the vanilla kernel sources?

TIA,

Richard
