Kernel Panic when attempting to reinstall OS X with Snow Leopard DVD

Dear Apple Community,

I've been attempting to do a clean install of Snow Leopard all day, no joy to be had. From using my copy of the dvd, to cloning it and booting it from an external HD, to borrowing a friends copy, it ends in Kernel Panic each and every time.

All I want to do is start afresh! Simulate that new computer smell. Crap-be-gone. The whole process is getting bloody frustrating.

Below is the log from the Kernel Panic. I really enjoyed writing it down and then typing it back up. If anyone at all has the faintest idea of what's going on, your assistance would be truly appreciated.

You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again.

Gripping stuff. Responses awaited, gratitude in advance.

Merci beacoup.
