[ts-7000] Build kernel module

Hello,
I'm new in linux and embedded and i'm stuck on a simple issue..
I'm using source for kernel 2.6.24 and i'm able to successfully build kernel 
and start it. I'm using ELDK build tools. But when i try to build a simple load 
module the process fails. I assume that there's something wrong with the make 
file but i'm not sure how to fix it... the make file that i'm using is at the 
end of this message.
I suspect that i should change the KERNELDIR but i'm not sure what to state 
there?
Best regards,
Blagoj
