I've got several of K6, K6-2 and even a K6-3 machines running FreeBSD.

Early K6 models have a problem with the cache and are unstable
if you fit more than 64 Meg of RAM.
(I have this CPU myself) 64 Meg or less and you are fine.
Actually, there is a software workarond and a linux patch to malloc
which actually fixed this.

I'm not aware of any K6-2 or K6-3 problems.
