The Orinoco PCI drivers in 2.4.20-xfs appear not to support Monitor mode.

On a semi-related note, has anyone tried either of the following:

1) Compiling and installing a new kernel - plus modules - into a mounted hard-disk partition while booted from CD? (When you did this you would be CHROOTed to the /source/KNOPPIX subdirectory, of course.)

2) Applied a different (non-2.4.20-xfs) precompiled kernel package to a CHROOTed source/KNOPPIX directory using dselect?
