Being an owner of both a Radeon board and a Mediator, I would totally help with this bounty, though in reading the whole thread, I realize that's not going to ultimately help.
I also wish they (Elbox) hadn't strong armed Ratte. I was following his development for a bit, then kind of faded away for a bit (got busy) then when I came back to check on it, the driver had disappeared and the whole crap had hit the fan.
I really do think the future is AROS (68k or otherwise) though, being a huge Open Source advocate helps.
On the note about wawrzon mentioning support for the nVidia cards. I believe at the very least that the earlier Radeon cards (7200 - 92xx) were one of the first fully supported chipsets from the earlier hardware accelerated mesa efforts. I recall it being nvidia-glx, then utah-glx (probably have those backwards), then radeon had full support. After that the OSS implementations seemed to dry up as both ATI and nVidia ended up getting more proprietary (licensed?) technologies in their cards, and so more closed specifications. Matrox (MGA) cards could be lumped in with that group as well.
The real question is, do Matrox and / or Nvidia make 5v PCI cards that are easily available to be used in a Mediator (assuming drivers were made)?
As a last note, I also must state that Elbox... WTF? We have to buy your hardware, does it really matter who makes the drivers for it? I even ended up buying a Spider 2.0 and a Radeon (which I ended up not using, and use one that has more memory on it). It's a shame that crap like this still goes on, but hey it is the Amiga community. Maybe I haven't been paying attention, but I don't see this much back stabbing and legal crap creep up in the Atari community.

P.S. I realized I necro'd this thread a bit, but it always kind of fits in an Amiga forum, I figure a few months isn't terrible.
