Tomshardware.com is reporting that Eran Badit editor-in-chief of ngohq.com has had some success running Nvidia’s CUDA platform and PhysX drivers on a Radeon video card. Apparently adding Radeon support to CUDA was not a big deal, but adding Radeon support for CUDA at the driver level is more challenging.
Badit says he needs support from ATI to finish out Radeon’s support for CUDA, but ATI has been slow to answer him, taking several days to reply. Surprisingly, Nvidia has been much more helpful and opened access to their Developer Relations and is providing assistance, including access to documentation, SDKs, hardware and actual engineers.
Nvidia’s official position is now that it doesn’t mind PhysX running on the Radeon an interesting change from when Justin Kerr reported that Nvidia wanted to license PhysX support to ATI pennies a GPU. This looks like additional pressure from Nvidia to make it’s platform dominant over ATI and Intel’s planned platforms. Third party implementation of CUDA on the Radeon is sure to rattle ATI’s cage.
Tom’s Hardware pinged ATI on the issue, but hadn’t heard anything back as of yet. The longer we wait for a competing platform from ATI, will only help Nvidia’s platform capture more market share. ATI looks to have an uphill battle against the already established
Nvidia is preparing to roll out full support for hardware accelerated physics on its high end graphics cards including the 9800 & 200 series. New beta drivers which enable this functionality can now be found using the advanced driver search tool. Version 177.39 installs PhysX drivers that will enable the graphics card to emulate Ageia hardware. Physics acceleration is part of Nvidia’s new CUDA initiative aimed at convincing gamers that graphics hardware is more capable and valuable then CPU’s. Games of note that currently support PhysX include Gears of War, Mass Effect, Rainbow Six Vegas, and Unreal Tournament 3. The list of supported titles is expected to grow exponentially as Nvidia rolls this feature out to older hardware in the coming months.

Computers are a cutthroat business, and often times compatibility has nothing to do with the technology at hand, but licensing agreements and corporate politics. All that stands between SLI on an Intel motherboard (or CrossFireX on Nvidia silicon) are drivers and a BIOS tweak. Don't believe it? Look at HP's Blackbird 002.
Now take that same concept and apply it to the heated GPU wars. With AMD gobbling up Havok and Nvidia acquiring AGEIA, the race is on to not only deliver the fastest graphics card, but physics acceleration too. Of course, developers would prefer one standard, and Nvidia indicated it would make PhysX available for free through its CUDA SDK, but if ATI had any plans of going that route, it appears they've been beaten to the punch.

Nvidia has reiterated that it won’t provide open source drivers for Linux. They claim that there is no need for it. It does however provides binary Linux drivers and has open sourced a few drivers.
According to ZDnet Nvidia said in a statement: “NVIDIA supports Linux, as well as the Linux community and has long been praised for the quality of the NVIDIA Linux driver. NVIDIA’s fully featured Linux graphics driver is provided as binary-only because it contains intellectual property NVIDIA wishes to protect, both in hardware and in software,”, which was in response to developers’ direct criticism of hardware vendors that produce just closed source drivers.
