It's no problem to add sparc64 stuff for me, but I wonder if
the prom_bootdevice passed from firmware is really SUNW,fdthree.
sys/arch/sparc64/dev/fdc.c uses "fdthree" (without SUNW,)
and several dmesg also shows fdthree too:
>> fdthree at ebus0 addr 3023f0-3023f7, 706000-70600f, 720000-720003 ipl 39
right you are. it's been a few years :)
