VIA has stated that they will work cooperatively with open source developer (mostly OpenChrome) to release their open source driver for VGA card. This was officially stated at Taiwan few days ago. What does it mean? It means that in the future, more support will be given to the driver as the driver is scheduled to be included in the next 2.6.28 kernel.
In the past, some people were complaining due to lack of support for VIA chipset. They can only depend of OpenChrome package which is part of XOrg, which can't fulfill their requirements. By collaborating with open source and include the driver on the main kernel tree, it can also boost their sales, because many people will eventually use it and they can find better support of it.
