The drive is not "new". It is "new" that this driver is available in source code. VIA already used this very codebase (plus some proprietary 3D and TVout bits) to build their closed source Xorg drivers during recent years. Those drivers were (and still are) available for certain distributions.
So this should explain that this is not "a new driver" but actually something that has been around for many years.
And openly publishing the source of this driver is obviously just the first step. Now all involved parties can look at everyone's source base, and can start a discussion on how to proceed from here.
I would rather not see VIA trying to build a new community around that driver, since that would further fragment the various groups working on VIA graphics support.
