That's a big regression from point of fbdev. Keeping it alive and working will be a tough challenge. 2d acceleration is a thing of the past and the number of people which are able and willing to put effort into supporting it will only decline. It has been a problem for a while already, basically it was dropped due to lack of support ... take care, Gerd
