Fred, as I mentioned in my private email to you, there are thousands of
differences between the 2.4 kernels and the 2.6 kernels.  The 2.6 kernel
is virtually a _complete_ rewrite.  Most of the internal structures
have changed.  The module interface is radically different.  Tweaking a
Makefile and exporting globals isn't good enough--the module must be
WRITTEN to conform to 2.6 specifications.

How to fix it is WAY beyond the scope of any quick mailing list.  You
should contact the module's author and ask if he/she intends to release
a 2.6-compatible version. Offer to beta test it if he/she is.
