One possibility is that sunlabel labels aren't sparc64-compatible.  (I
don't think this is very likely, but it needs mentioning - I haven't
done enough sparc64 stuff to have much familiarity with them.)

The next possibility that comes to mind is that your disk isn't on
/sbus/SUNW,fas@e,8800000/sd@0,0.  There are only two ways this seems at
all likely to me.  One is that someone else had the machine before you
did and set up nvramrc to stuff a different device - probably on an
external SCSI card - into the "disk" devalias.  Might be worth checking
"printenv" in OFW to see if nvramrc contains anything and whether
use-nvramrc? is set.  (I'm assuming sparc64 OFW works like sparc32 OFW
in this regard; ICBW.)  Two is that the device isn't at SCSI ID 0 -
check probe-scsi, probe-scsi-all, and/or what netbooted NetBSD says
about the device's target on the SCSI bus.
