What you mean is: we finally gave up on fixing this in Debian and decided to
just direct everyone to use the Anheng repo packages, which btw are available
since ages ago, and howto on that [1] was published by me in March-2011.

Not that this is particularly bad, just for some factual correctness. :)

My benchmarks of Debian O32 vs Parabola N32 have shown a difference of about 8%
in the very best case in favor of Parabola.

The N32 experimental port of Debian [2] is defunct since a long time ago. And
8% was way far from being enough to justify switching distros from the familiar
Debian for me.

As for Gentoo, I don't know, is there even a way to use it on the Yeeloong
without having to personally compile every singly package you install?
Because that's certainly not what I would want to do on a slow netbook.
