I'm sure, based on my prior conversation with Cox, that Red Hat really
has absolutely _no_ interest in supporting i586 out of sheer marketshare.
It's either i486 (i386) or i686 for them.

Unlike i486 and i686, i586 is a _specific_ (and partially buggy**) product --
namely original Pentium and Pentium MMX products and _no_ other.
All subsequent Intel products (Pentium Pro on-ward) have been i686.
And _all_ clones, cores, etc... have either been i486 or i686 ISA compatible.

[ **NOTE:  I'm not talking about the FPU bug.  That was minor compared
to many of its other bugs and, even worse, some real design flaws in the
ALU and control. ]
