It won't be in mainline as far as I am aware. > And since I know the Genesi guys read this list, does the Kernel+OpenSSL > combo that comes with Efika have this enabled as standard?

I recall Matt enabling the option, I can't recall if it's in 2.6.31.14.20 or not, it's definitely enabled in the mx51_efikamx_defconfig if you checkout the latest from gitorious.
