As for the first issue, ill take a look a see what im actually dealing 
with. Like i said, i'm working clang/llvm for illumos but that's an 
entirely different beast.

I have access to quite a lot of sparc gear. V215, T1000, T5120, M4000, 
E6K, Netra X1, and a few more. I don't mind hosting a couple of them if 
anyone in interested in doing some work on them.
