I spoke too soon.  Even with my patch, the compiler complains.
The three options to fix this are:
- remove the -O2 flag
- change -march=i386 to -march=i686
- use gcc 3.2 compiler for everything

Changing the compiler on my system is not what I want to do right now.

It turns out that if you do:

rpm -bb mykernel.spec

then for some reason, rpm will default to building for the i386 platform,
and supply the -march=i386 flag during the kernel make.

The way to override this is to do:

rpm --target i686 -bb mykernel.spec

I'm going to rebuild everything now and see how it goes....
