For this hang, Solaris is stuck trying to set and verify a bit which is
currently un-settable in qemu.  It's the MMU breakpoint action register
(asi 0x4c), and if bit 12 is set, then it should continue on just like
with SS-5.  After fcp0, the next thing Solaris should initialize is the
network:

pseudo-device: fcp0
fcp0 is /pseudo/fcp at 0
Using RPC Bootparams for network configuration information.
