Sorry, your summons got lost in the ether for a while. [REDACTED, SEE EDIT]
I don't think much has changed between the kernel used on the Flo image now and the canonical one. I think it's just the rootfs that's been updated.

Edit: I did some cleanup on my kernel tree. It's now buildable, the reason it wasn't prior was because of a driver the elementalX stuff pulled in (which is broken right now, not sure why yet) and I hadn't mrproper'd before commiting (what a moron I was).
Kernel Tree: http://github.com/ShadowEO/TonoKrnl
The kernel has the standard Android CPU governors available, however Vivid's init seems to set it to ondemand, as well as binfmt_misc (It is possible to run WINE with some sorcery under recovery to enlarge the system image, and then install the components to the system image, WINE will not run under Libertine because of proot, which it uses to set up a unprivileged chroot)
Anyway, the kernel is indeed buildable, I'm running it on my 15.04 N7 right now. Perhaps I should make a thread for the kernel on here now that it's buildable, might be able to get some help with it (cleanup, optimization, etc), not sure how well received it will be though, what do you think @doniks? (Btw, was playing around with the Mainline kernel, postmarketOS, and a couple other distributions [using a modified ramdisk to boot from a directory on /data], the mainline kernel is pretty cool, but I couldn't get USB working and postmarket has no onscreen keyboard functionality.)
