It would be interesting to boot directly the PowerNV machine from a

AFAIK there are no minimum initrd images available. The closest thing
would be the "bootonly" ISOs that can be found in the links below:

But to avoid using skiroot, you would need to manually extract the
kernel from the ISO and also specify the rootfs, using something like:
"-append cd9660:cd0".
If you don't want to emulate a disk or cd, the ISO can be passed to
-initrd and "-append cd9660:md0" may be used to tell FreeBSD where to
find the root partition (it loads it as a memory disk).
There are also qcow2 snapshots available:

But you'll also need to extract the kernel from the image or from
kernel.txz to boot them.
As these images target pseries and lack a FAT32 partition, Petitboot
won't be able to boot them.
Alfredo (cc'ed) was trying to make them Petitboot compatible.
