I totally haven't followed the details, but there seems to be a lot of bad blood between VIA and huge egos behind the *chrome forks.
Whatever happens, VIA needs to develop the driver in the open perhaps in X.org git repositories like all the other drivers.
December 2007 AMD's geode driver was in similar bad shape, with no community coordination or public mailing list of its own. I kicked AMD, and Jordan Crouse moved their previously internal AMD mailing list to public at X.org, and we together wrote all information plus the roadmap on an X.org wiki page. VIA must take steps like this to fully engage with the community, or they will never compete with the competition and achieve "Just Working" drivers shipped in all Linux distributions by default.
