Hmmm it looks from reading the source code that QEMU doesn't actually implement a proper audio device for SS-5 at all but merely provides a dummy device with an empty mapped region. In that case it may be possible to provide a simple mapping in OpenBIOS to match the one in QEMU which may be enough to persuade Solaris to boot.
Ugh. I recall that audio chip being non-trivial...
It might be worth deleting that audio device from the device tree and see if Solaris really does get further.
I've tried the same CD image with the SS-10 QEMU machine, which seems to lack the audio device, and I still hang. I get the first part of the kernel, no extra logging, and then the spinner to infinity...

Does anyone know what loads on a real SS after the audio device?

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@0 Using RPC Bootparams for network configuration information. le0: No carrier - cable disconnected or hub link test disabled? le0: No carrier - cable disconnected or hub link test disabled? Skipping interface le0
