With the DN2800MT card (Atom 2x1.8Mz with Cedar Trail technology), ubuntu 12.04 LTS works fine except graphic acceleration.

Ubuntu automatically install a gma500_gfx module and the cedarview-drm package, but the activation from system parameters fails. This driver needs the cedarview_gfx module (installation fails, please consult /var/log/jockey.log).

I tried to build the ubuntu kernel 3.2 with the intel driver patch (https://downloadcenter.intel.com/Detail_Desc.aspx?lang=eng&changeLang=true&DwnldId=21938), build OK but not works ([drm:cdv_intel_dp_complete_link_train] *ERROR* failed to train DP, aborting from kern.log). With the linux kernel 3.8, the intel patch fails :

$ tail /var/log/jockey.log :
