First of all, in the kernel config where you enable loadable modules, 
use the settings below:

[*] Enable loadable module support
[ ]   Set version information on all module symbols
[ ]   Kernel module loader

Also, try applying the attach patch, from the linux-2.4.x directory, 
with "patch -p0 < jw-modules.patch"

Try this and let me know.

Cheers,

John
