At this point it would be better for all the targets (including N900) to standardise on a modern version of xorg. N900 would use xserver-xorg-video-fbdev ported to modern xorg along with the reverse engineered wsegl dri2 blob modified as necessary. (and maye be changed to use omapdrm later) Android targets could use a hwcompositor ddx plus appropriate egl glue. And so on .
