No just download the latest kernel source from www.kernel.org and you
can compile it and boot from it.
And later you can do all your _geeky_ stuff there...
You can always boot to your original(previous) kernel as and when required.

Simple, download a new one !!!!
And also, FYI, Once you have build your kernel image, you can modify
the sources to build a new kernel image. It won't hamper your previous
image.
But, if you wish separate source, then grab one from www.kernel.org.
