I'm not quite sure what your point is there: I can't see any other mentions of Athlons or i686s, but a Duron is simply an Athlon with less level 2 cache [1]. Architecturally, and from a compatibility point of view, they should be identical, and fully compatible with kernels compiled for "i686" machines.

[1] OK, it got slower bus speeds than some Athlons...
