Yes, the specfile still supports the i386 build. I have to build a kernel 
package for the RULE installer, I use:
rpmbuild -bb --target i386 --without BOOT --without smp --sign 
kernel-2.4.spec

Correct, RHL-9 it isn't supported on anything less than an i586. Neither 
was the 8.0 release.

I believe the default flags are:
- -O2 -g -march=i386 -mcpu=i686
Which is as you said, i386 compatible, optimized for i686

The 7.3 release did contain an i386 kernel package:
$ whichcd -v 7.3 kernel | grep i386
CD-1:kernel-2.4.18-3.i386.rpm

However, it did lack an i586 (UP) package. ;)
