No idea - I don't have many Solaris images for testing at all, so just 
try it and see. Although you need to wait for the fixed binaries to hit 
the QEMU 1.7/master git repo to fix another outstanding SPARC boot bug.

That's because the boot parameters are passed to the PROM via a QEMU 
custom FW interface (which OBP has no knowledge of) rather than by 
having QEMU emulate the NVRAM in exactly the same way as real hardware.
