R600 Vulkan Driver
According to various forums and sites, a Vulkan driver for Terascale is possible: but will require an inordinate amount of dedication to create and is highly complex and undesirable as a project. Therefore, I am opening this issue in the hopes someone exists with the passion to tackle the impossible and to create for the forgotten.
Even if this only supports HD 5000 / HD 6000 cards it is still a seriously good use of code to prevent the end of life of quite a bit of viable hardware (especially the 2GB configuration).
