Thanks for your time and suggestions,I solved this problem,
I added the two modules in kernel dir(driver/misc/),updated
Makefile,Kconfig file & compiled, loaded the m2 and m3 to my surprise it worked,Other things I observed is even when I compile two diff driver's with two diff version of GCC(4.2 & 4.3) I was able to insmod
and it was working fine(I thought kernel version (2.6.32.9) & gcc version(gcc-4.3.1) should be same,),I am really puzzled with android kernel????????,I realy dont know how it is working,Please correct if I am wrong
