tiny6410 connect to capacitive lcd, thouch not work.

Hi
I connect my Capacitive lcd to tiny6410 and install linux on it. I also
change the friendlyarm.ini to this:
#This line cannot be removed. by FriendlyARM(www.arm9.net)

LCD-Type = S70

CheckOneButton=No
Action=install
OS= Linux

VerifyNandWrite=No

StatusType = Beeper| LED

#################### Linux #####################
Linux-BootLoader = Superboot-6410.bin
Linux-Kernel = Linux/zImage
Linux-CommandLine = root=/dev/mtdblock2 rootfstype=yaffs2 init=/linuxrc
console=ttySAC0,115200 skipcali=yes ctp=2
Linux-RootFs-InstallImage = Linux/rootfs_qtopia_qt4.img
Linux-RootFs-RunImage = Linux/rootfs_qtopia_qt4.ext3



and play with ctp=1 (not work),ctp=2 (not work),ctp=3 (not work)
my lcd is S70(when linux is install it writes on screen lcd type is S70
(auto detect))

this device has resistive lcd at first but it was broken then I changed it
to capacitive lcd but touch not work .

I found this LCD driver is not install. I don't know how to install this
LCD driver.
when I use the LCD with 3 buttons and boot, nothing show on screen.
I change the other 7" LCD (both of them are capacitive), touch not work. I
check this "# ls /sys/bus/platform/drivers
A samsung-ts must be listed in this directory. If not, the kernel must be
re-configured to support this device." in this PDF in this URL:
http://www.pengutronix.de/oselas/bsp/pengutronix/mini6410_bsp_en.html.

so how can I reconfig kernel. I check all devices in this directory in
kernel menuconfig: Drivers>input drivers>touch>mark all of them and make
zImage, and copy the image to SD and put on mini6410 but nothing happen.
(no LED flashing)
I am confused. please help me
