So I installed a Retail version of Snow Leopard on my D430, installed greatly (took 1 hour), after a reboot 
it booted in some stripes, after a time the song came on. I changed to my external Screen (my internal is broken), 
and the Screen seemed ~100px to low and twice the height of the screen. 
I have the 1.2 Ghz on, 2 GB Ram and a Intel and an Atheros Wifi chip.
