I see.

So I don't even need sparc64.

So, stick the sparc boot into /, then configure /dev/sd0d (on /boot64)
with the sun4u bootstrap:
# installboot installboot -nv /dev/rsd0d /boot64/bootxx /boot64/ofwboot

I'll try that tonight. I assume the sun4u kernel needs to be on the same
partition as the boot blocks?
