But then give the firmware a clue, and fix it. For the partitioned
case, I'm sure you have ways for an alpha partition to define the
characteristics of a guest partition, and/or a small controller image
running in your hypervisor for similar purposes.

If the kernel needs to set "what works best for it", then you should
look into some of the ELF header flag stuff that IBM pSeries firmware
architects seems to love these days, it seems to be the preferred way
for the OS to tell firmware/hypervisor what it wants.

There should be no need to introduce yet another interface for this. There
are plenty of them already.
