I have successfully programmed the AT90CAN128, based on the mega128
example and some
small modifications.
Could you repost those modifications in the form of a patch?
You can generate patches using
diff -NaurP old.c new.c
and similar for non-C files ... use the full path from the root
of the source tree.

Yes. Here is the patch and the new cfg used to test (almost just a
copy of the one for mega128)
