The 32-bit kernel is capable of running NetBSD/sparc a.out executables (in
addition to 32-bit ELF, SunOS, SVR4/Solaris, etc. like the standard
NetBSD/sparc kernel).  The standard NetBSD/sparc toolchain is capable of
generating these sorts of executables.  

Generating kernels is a completely different matter.  What you need to do
is use the NetBSD/sparc toolchain to build a gcc/egcs/binutils toolchain
that can generate sparcv9a (sparc64 in GNU-speak) which are pure 64-bit
binaries for the 64-bit kernel or sparcv8plusa which are 32-bit with
UltraSPARC extensions for the 32-bit kernel.

The tools in the -current tree seem to be able to generate proper 64-bit
executables except that they are calling __start instead of _start (you
need to change crt0.s).
