 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 
 >> not configured
