Arduino IDE and Xandros (Debian-like) on eeePC 701

I just got my eeePC 701 out of hibernation and was wondering if I could use it to code my Arduino.

The answer is yes according to the playground and the forum but it seems "http://www.uk.debian.org/debian" has been moved and I don't really have a clue as to what repository I'm supposed to use.

Anyone got time to give me step-by-step guidance?
