Oh yeah, for those that are impatient, lack caution, or are just interested in the code, I'm attaching my K2 screen saver hack. It works for me, but I can't guarantee it won't DESTROY YOUR KINDLE 2.

Honestly, if you can't view the source code and understand what it's doing then you should just stay away.

And if you're still around after those warnings:

Code:
==============================================================================
WARNING: Use at your own risk!  This is an UNOFFICIAL update to allow custom
Kindle2 Screen Savers.  This file is NOT from Amazon.com and any harm it
causes your Kindle2 will be your own fault.
==============================================================================

Instructions for use:
---------------------
1) Plug your Kindle2 into your computer.
2) Copy "Update_kindle2_user_screen_savers.bin" to the root of your Kindle2.
3) Change directories to the "system" folder.
4) Create a new folder called "screen_saver"
5) Place any 600x800 PNG image files into the system\screen_saver folder that
   you just created.
6) Unplug your Kindle2
7) Press the "Menu" button on your Kindle2 and select "Settings."
8) At the Settings page press "Menu" again and select "Update Your Kindle."
9) When the "update" is done your Kindle2 will reboot and you are done.


To go back to the default Kindle2 screen savers:
------------------------------------------------
1) Plug your Kindle2 into your computer.
2) Copy "Update_kindle2_restore_default_screen_savers.bin" to the root of your
   Kindle2.
3) Unplug your Kindle2
4) Press the "Menu" button on your Kindle2 and select "Settings."
5) At the Settings page press "Menu" again and select "Update Your Kindle."
6) When the "update" is done your Kindle2 will reboot and you are done.


More Information:
-----------------
You can change images at any time, but you must reset your kindle for them to
appear (press and hold the slider for 15 seconds).  If there are no images 
then a blank screen will be shown when you go into sleep mode.

It's possible that images in other formats besides PNG work, or in other
resolutions besides 600x800, but I wouldn't know.

After the update, the update bin will be gone, but there will be two new
files in the root of your kindle: "framework.mario.conf.orig" and
"framework.mario.conf.new"  You can delete these if you want, they are
simply copies of the config file (before and after) the screen saver
directory was changed in it.

The "src.tar.gz" has the code (modified from Igor Skochinsky's code) to
generate the update bin yourself.  You can see that all the update really
does is a single sed(1) command to change the path of the SCREEN_SAVER_DIR
variable.
