How has it been proceeding, specifically?

"I have not yet begun to compute" on this machine.  So it's a little
early yet to surrender ;-)

Anyway, I still have the edgy kernel sources, so I should be able to
do that build here and apply the undervolting patches to that.

I believe the HOWTOs I've found are all using it.

Ahem.  When you reach true old age, like me, you may find yourself
getting fussy about how hot your laptop gets, how quietly it can run,
etc.  I bought this machine because there were too many annoying
things about a MacBook pro.  I need to make it work better than one of
those or it will all be for naught.  So even if I don't end up using
the new kernel much, it's important for me to know now how well it
*can* work.
