It's been there for quite some time and no progress have been made for
the time I've been tracking it. Seems abandoned to me and my impression
is that that one is scrapped in favor of vmwgfx... Do anyone know if
vboxvideo is suppose to be in working state (the one in linux kernel)?

vmwgfx seems like the better choice if it's used by both vmware and vbox
(v6+). But if it's suppose to be in a working state I can take a look..
