There are plenty of people who would donate a virtual machine or remote work environment for this sort of thing, if anyone was (seriously) interested in porting. Realistically, I doubt anyone wants to put that kind of effort in. Getting FreeBSD and more recently OpenBSD working on PowerNV platforms has taken a very large effort by the community, and those OSes already had some support for POWER/PowerPC. Illumos only has the x86 and (very bitrotted) SPARC support AFAIK, I believe there have been some attempts at bringing up ARM but don't see anything substantial.

More on topic, as someone sentimental for SPARC hardware and to an extent solaris, this is sad to see, but it feels like just a formality. I don't think illumos has worked properly on SPARC hardware since ... Ever? There were a few illumos distributions with SPARC builds but I always had trouble getting them to run on even a T2, seems there was little work done post rebranding from OpenSolaris for SPARC. Linux and OpenBSD have been much, much better on SPARC than Illumos, tinged with bitter irony...
