What flags does RedHat use to produce their packages (what is their rpmrc
definition for i686)?  Is the kernel spec file smart enough to change
.config in the kernel sources directory so that it's building code for i586
rather than for i386?  There's a lot more to optimizing the kernel than
there is any normal user space program.
