What is this sysctl reporting ? The kernel architecture or the system's ?
A 32bit kernel on a 64bit system is sun4u but is NOT sparcv9.
In either case, I'm starting to think that reporting "sun4*" is incorrect,
also, we have the potential to be compatible with isalist/optisa on Solaris
which used sparc* rather than sun4* to report and represent ISA.
