Code has been given to XFree86 that supports TGA and TGA2, which came from
(reasonably close to) the production Tru64 servers for those cards. If you
(or anyone else) are serious about this, please contact them.

And what makes these cards more "Evil" than most of the recent PCI VGAs?
In my experience, these typically have separate VGA core from the accelerator
core, unlike older ones which attempted to extend VGA in every conceivable
non-standard way... ;-}
