Maybe I'm going the wrong way about it, on sparc64 web page is says:

"NetBSD/sparc64 supports both 32-bit and 64-bit kernels. A 32-bit kernel 
runs all NetBSD/sparc binaries"

So I guess the question would be: what's the best and correct way to 
build 32-bit kernel for sparc64 architecture and what's the best way to 
integrate it with 32-bit userland? Anyone tried this before?
