Multimedia :: Can't build webcam driver

I've been trying to build a module for a Logitech webcam using the uvs driver - the problem is when I try to cbuild the driver, I get the following error:

$ make
Building USB Video Class driver...
make[1]: Entering directory `/KNOPPIX/usr/src/linux-2.4.26'

The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

make[1]: *** [modules] Error 1
make[1]: Leaving directory `/KNOPPIX/usr/src/linux-2.4.26'
make: *** [uvcvideo] Error 2

The "present kernel configuration" obviously does have modules enabled - is this governed by some kind of flag I can check/set?

Is the .config present in there? It may check for that (you open up the Makefile script to be sure of what it does though)
