linux driver update for a specific video board

I have a video board (3DLabs Wildcat III 6210) that is no longer supported by the producer. On their website you can find drivers for this particular board, up to RHEL3, but none for RHEL4 anymore. The bid is this: make the existing drivers for RHEL3 work on RHEL4. Not even sure if it is possible at all, but I thought I'd give it a try. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) The work should be released as GPL *if* possible. ## Platform Linux, RHEL, CentOS
