Intel "The Intel 965GM Express Chipset represents the first mobile product that implements fourth generation Intel graphics architecture. Designed to support advanced rendering features in modern graphics APIs, this chipset includes support for programmable vertex, geometry, and fragment shaders. Extending Intel's commitment to work with the X.org and Mesa communities to continuously improve and enhance the drivers, support for this new chipset is provided through the X.org 2.0 Intel driver and the Mesa 6.5.3 releases. These drivers represent significant work by both Intel and the broader open source community."

On all of these *nix systems, the majority of the driver support lives in userspace and interacts with the driver interface in the X server, which is under a non-copyleft, non-share-alike license. The part that involves the kernel is the direct rendering code, which interacts with the DRI framework. To get around the linking problem with the Linux kernel, this part of the nVidia driver lives in userspace and talks to a GPL shim layer that they load into the kernel. If the DRI changes, they only need to update their shim.

FreeBSD and Solaris face challenges because Linux DRI is advancing beyond their capabilities, mainly due to contributions from Intel. FreeBSD and especially Solaris are mostly locked into the frameworks they have. This is the double-edged sword of stable interfaces. As nVidia works to keep their shim in sync with Linux DRI, it becomes a hassle to continue to support these other kernels.

In his "infinite wisdom," Linus decided that eventually people's patience with--and trust in--proprietary drivers will run out, making stable in-kernel interfaces a non-issue. The Linux kernel development model works great for OSS drivers, and most hardware will eventually be supported by OSS drivers. Our suffering is temporary and for a good reason.
