Touchscreen not working

Hello,
I Got my Mini 2440 board(1 GB)with the superboot installed on it. I used 
http://www.friendlyarm.net/forum/topic/5391 these instructions to convert
it to suppervivi and use DNW to transfer zImage. I used zImage_A70 and
zImage_A70i present on DVD transfered using DNW. Before that I transfered
supervivi-128M. But the problem is my touchscreen is not working. Touch
calibration program opens at start but it doesn't respond.  

Anyone with same issue or with solution for this??

Hi Ajit,

What is ur LCD Model? You have to load the zImage of the particular model
Compatible LCD only.

Now Touchscrren Driver Changed as compare to previous.
So you need to used new kernel source code and then compile kernel and used
that kernel.
