I'm sort of with Roland on this, the timelines aren't usually worth it
for a company to bother especially with complicated hardware, the time
taken to do a community graphics driver for any GPU where specs have
been available approaches infinity, unless the vendor actually does
the driver or pays someone to do the driver the hope of a community
supported driver reaching maturity while the product is still
available is slim.... for anyone desparate to start writing device
drivers, XGI have recently dropped a load of specs for their cards,
I'm not seeing anyone other than the usual GPU ppl step up an do
anything and as I said the time it takes a single volunteer to write a
GPU driver is a lot longer than the card...

Dave.
