Thanks, partly applied:

OK, applied.

Actually, there is need for that. I reverted your previous patch that
removed the need.. ;-). INCLUDES is still used when compiling with 'make
pccard'; this is needed for Linux 2.2.x and is optional for Linux 2.4.x.
In other words, this part of the patch was not applied.

Yeah, kernel version should be available more cleanly.. linux/version.h
is not very good place for it due to distribution-specific changes
(e.g., look what Red Hat did to this file). Parsing the version from
Linux toplevel Makefile might be better alternative. We just need to
make sure that the code doing this works with Linux 2.2.x, 2.4.x, 2.5.x
and preferable with most distribution-specific changes..
