Phoronix: S3 Graphics Responds About Linux Support
Last week S3 Graphics had released the Chrome 540 GTX, which is their newest and fastest PCI Express graphics card. Similar to when announcing the S3 Chrome 540 GT, in the Chrome 540 GTX press release they once again mention Linux support along with OpenGL 3.0 capabilities...
I don't know who will buy that card. It is not really much cheaper than something from Nvidia or ATI and you can expect that the driver is not really optimized, not even for Win. All VIA/S3 chips before are lowend (onboard mostly) chips, nothing really worth to talk about.
What I understand from the article is that they're releasing a binary kernel module, no source, and labelling it GPLed to get around the kernel build scripts that check for licence compliance. If memory serves me right there's kernel devs who take things like this very seriously.
