If the poster being referred to is me, that wasn't what I meant to say, or rather what I meant to be *understood*-- what I meant was that apparently the Handbook recommends using the k8 flag, but people using that flag seem (and I stress "seem", as I don't follow this issue that closely, naturally) to be running into problems, whereas those using the amd64 flag are not (or at least not the same problems). Now, I don't know the truth of the matter, but that would lead me to suspect that there could be *outdated information in the Gentoo documentation* (thus, a "documentation bug"), which, if those affected can verify, should perhaps be submitted.
