The module build and loading system has been changed from kernel 2.5
series so the old build system of kernel 2.4.xx series wont work on
kernel 2.6.xx series. So the Makefile or make command you are using
wont work for 2.6.xx kernel and you have to compile kernel with
command :
make -C /lib/modules/<kernel_version>/build M=<your_source_path>
And for more details do look at driver-porting from 2.4 to 2.6 kernel
articles from the link http://lwn.net/Articles/driver-porting/ and
more specifically for makefiles take a look at article this
(http://lwn.net/Articles/21823/).
Also make sure that your module (code) will be for kernel 2.6.xx
series and 2.4.xx series wont run (or at-least not successfully) !
