I myself could solve the problem. Basically what was happening is I didnt
include linux/init.h so things were messing up somewhere in
module_initialization.
btw i get following warning in module compilation. Any idea what it is
for?
Warning: Ignoring changed section attributes for .modinfo
gcc 2.96, kernel 2.4.1, flags -DMODULE -DMODVERSIONS -D__KERNEL -Wall
