Also ties server releases more tightly to kernel support, especially
un-fun for those running a kernel that's not Linux (i.e. BSD & Solaris).

I was able to ship older Intel drivers that still supported UMS, while
waiting for KMS support to land in our kernel.   If Radeon similarly
goes KMS only, I'll probably have to do the same for it for a while,
since DRM porting to another kernel is no small/quick task.
