My Kernel Module

Guys,
I have created a very simple kernel module that controls an interrupt pin
on the GPIO.  I am using pin number 9 on the CON4 header as an interrupt. 
That's all I want to do is manually set this pin high so the interrupt is
triggered, and then physically set it low so the interrupt is not triggered
anymore.  When the interrupt is trigged it prints messages out to the
console saying so.  I got the code from the chinese manual and modified it
to my needs.  I also followed the instructions in the chinese manual
(Chapter 7) to compile the driver against the current Kernel and also to
compile my driver userspace program.  When I telnet into the ARM board, I
do the following commands after I transfer the ".ko" file and my binary
file to the board...

modprobe interrupt_driver
mknod mydriver c 253 0   (if you look at what the kernel prints out it says
the major number is 253)
(I then "CD" to the directory of binary executable and then...)
chmod +x myDriver
./myDriver

After that last command, nothing happens at all....  Attached is my code. 
Can you get it to work on your mini2440?  Any help would be appreciated. 
Thank you!


Attached is my C code for the Kernel interrupt driver... I'll try to attach
my userspace test code on my next post.

Here is the userspace interrupt test C code.  This program basically reads
the interrupt and prints messages to the console.  Again, any help would be
greatly apprecaited.  Thank yoU!
