You need to copy the kernel itself and the modules.  The kernel can be found 
in /boot and normally starts with vmlinuz.  The modules can be found in 
directory /lib/modules/<kernel name>.  <kernel name> is the output you get if 
you run "uname -r" .  And this can probably also found in the name of the 
kernel.
To be able to boot the kernel, you have to update the bootloader (lilo or 
grub).  If you use debian, you can use update-grub to update the grub config 
file (it scans /boot for kernels).  It's possible you can run it on other 
distributions too.  I don't know.

What I do, I always leave the kernel in place that is installed by the 
distribution and add my own custom kernel.  So I can choose at boot time the 
kernel I want to boot, and of course, I make sure my kernel is listed first.
