I do not have much progress to report. I now have a test image on a
SD card to make experiments with drm and a new still quite empty
module for glamo. We have to make modifications to drm and bypass
all pci related code. Since I also have a checkout of drm/dri/mesa from for the nouveau driver, I discovered that the drm
module also differs in many parts to what is currently found in andy-tracking.
