Please check that you are using the right C-Compiler. The "default" gcc
may not be the one used for kernel compilation. Check with "modinfo",
your own modules as well as the ones that are already compiled.
Again, I'm 100% sure that you have the right kernel sources and config
in /usr/src/ in the Knoppix image, because I used these to compile the
kernel. Maybe, the vmware-install.pl script is not aware of kernels past
2.6.16 yet, and forgets to add essential information for creating
modules?
Kernel and some modules are stored in the uncompressed CD/DVD part,
/boot/isolinux/ for the Kernel and /KNOPPIX/modules for modules that are
needed at boot time after the CD/DVD is mounted (i.e. cloop and
unionfs). Note that this last part has changed, it is an additional
feature that you can now store modules directly on the DVD without
changing the initrd. Makes testing of new modules easier.

Excuse me for being fussy, but, they are NOT "free". Nothing against
your motivation to add new and exciting stuff to Knoppix. ;-)

You can hardly call that "free". Or, maybe you mean the "VMware Player
Distribution Agreement"
http://www.vmware.com/download/eula/player_distribution.html, which
states:
"2. Reproduction and Distribution License.
2.1 Subject to the terms of this Agreement, VMware grants you a
non-exclusive, non-transferable worldwide, royalty-free license to

2.1.1 You must obtain VMware's prior written consent for each

...
I won't do that either. Forthermore, it would put an additional burden
to everybody remastering Knoppix and creating derivates, namely, either
removing the player or obtain a "written consent" from VMware.
I know that qemu is really slow compared to VMware (even if we would use
the proprietary kqemu kernel accellerator), but its license is
acceptable for me, whereas vmwares license is not. So, we added a qemu
version built with only free software components to the DVD version,
which means that windws users can now boot Knoppix within Windown to get
an impression of how it should run when booted from DVD (just at least
four times as fast).
