I don't recall phrasing it that way, but indeed #address-cells is specific to 
physical addresses. I might guess that back in 32-bit forth, the virtual 
address would be 4 bytes, but that predates me (by 1994, we were doing 64-bit 
forth). I'd expect any recent Solaris to believe OBP is 64-bit. Matter of 
fact, by Solaris 2.4, we were already doing 64-bit, why are you running into 
32-bit with Solaris 8?

By the way, have you seen P1275.1/D14a, Supplement for IEEE 1754 ISA (SPARC)? 
It talks a lot about issues you've been dealing with recently (lessee - that's
