We should make this the new punishment if you don't submit your Secret Santa gift on time. Much worse than being banned 

Haha, love the april fools joke. So disturbing 

There is a function in windows called MouseKeys that let you control the mouse cursor with the num pad. It may not be the solution you wanted but you might as well try it out: http://www.microsoft.com/enable/training/windowsxp/mousekeys.aspx

Maybe this book: http://www.blendernation.com/2007/01/12/free-book-designing-arcade-computer-game-graphics/ will help you.
I don't think you'll learn any specific pixel art techniques from it though (I read it a long time ago, so I don't really remember) but it may be helpful anyway. I remember it had some really good explanations of the technical side of pixel art (screen modes etc.) and it also contained some interesting interviews with old sceners. And it's free so you have nothing to loose.

This old book may also have something to say about the subject too: http://www.amazon.co.uk/Using-Deluxe-Paint-Steven-Anzovin/dp/0874551706?tag2=gp04-21 

But seriously, I don't think a book could teach you how to become a better pixel artist. I think the best way too learn is to work on your traditional skills until they're really solid and then study some works from you're favorite pixel artists.

Thanks. I ask because I'd be interested in doing something like Kenneth's and your work as well, but I'm not exactly willing to shell out money for such a high-end application (+ huge learning process?) if I only want to be able to experiment with low poly models and stuff, heh. 

I can really recommend Wings 3D. I don't know how well it handles textures but it's awesome (better than 3d studio max) for low poly modeling.
