You cannot do that like that. Not only HyperSparc is version 8, plus sparc32
is usually compiled to run on all 32bit SPARC platforms (ok, no sun4).
So if you'd like to, you need runtime test for HyperSparc.
But I guess if PIO download is done always, it should not hurt and save some
kernel code.

Cheers,
