Dave, is my understanding correct that the custom kernel is only used for changing voltages and under/overclocking?

If you can change the kernel you can then compile the entire os from source and add all the bells and whistles as Cyanogen does. Without the kernel you cannot do this, yes you can have custom roms but just ask any of the rom devs for x how much harder it is too add hacks like they have in cyanogen or many of the other droid roms compiled from source. The kernel is linked to the framework and without being able to change both you are limited in what you can do.
Thanks for the feedback.
