AMD AM2, Intel whatever

Generally there has been some notice. There was a significant discussion when we stopped building 586 kernels and what options were used for 686 builds.

I don't think we had an announcement here when upstream dropped 386 support, but we weren't doing builds for those CPUs in Fedora for a long time before that change happened.

There have also been some CPU relevant changes in software graphics support used as a fallback in gnome. Not all 686 machines support the exact same instruction set and I saw some issues on an AMD CPU (an Athlon MP). However, with CPUs that old, the software graphics fallback for gnome is not very usable and you'll want to use another desktop.

Probably the next change to kernels to look for, would be the end of non-PAE kernel builds. I haven't heard any serious discussions about doing this, but that will affect some machines. I have a laptop that can't run PAE kernels (with a Pentium M CPU).
