The ltsp version included with lenny does not work with 32MB Ram. I had several thinclients which were unable to boot (long before starting X). Upgraded to 64MB they worked, but I recommend 128MB for Thinclients to run smoothly. That's my experience from several German schools. Best wishes, -- .''`.
