How about "not building a prep kernel at all"?
The Open Hackware bootloader used by QEMU insists on a boot partition, even
when I use "-kernel" to use the built-in bootloader. But the prep kernel is
apparently formatted to look like a boot partition, or close enough for the
firmware to recognize it. (The macintosh-style kernels require a hard drive
image in order for the firmware to like them. So I can't boot one of those
with "qemu -kernel filename" even if I build it right.)
