Current l-m.o tree has vr41xx support thanks to Yoichi, that's the best starting point. But as you said, support for the board itself is not there as a whole, there were some drivers for kbd/tpanel/fb around from an old project (not linux-vr), just gotta look for them. Afterwards, just mix the ingredients and bake the pie. Ricardo
