This machine is sold with Linpus Linux pre-installed.
Running Debian Squeeze doesn't work properly due to the graphic card (ATI Technologies Inc NI Caicos [AMD RADEON HD 6450]) which need kernel >= 2.6.38, video-ati/radeon >=6.14.0 and Mesa driver >= 7.10 (7.11 is better).
With current Debian testing (Wheezy) this machine works perfectly.
