I'm running squeeze on a 2003 IBM T40 - also 2Gig. It runs fine and runs Lotus Notes fine as well. I'm backlevel because Notes is broken on the latest Gnome. It's just a machine I use to boot, look, shutdown and it's wonderfully fast for that. Replaced Windows XP which was a pig and going out of service. I actually tried Ubuntu but it has piggish tendancies as well!
