All .rpm files are created from .src.rpm files.  These are called SRPM or
src rpm files.  They contain the source code and other files used to build
rpms.  There is a file that controls this build called the .spec file.
These for redhat are placed in the /usr/src/redhat/SPECS/ directory.
The kernel-source-2.4.21-27.0.1.EL.rpm is created by rebuilding from the
kernel-2.4.21-27.0.1.EL.src.rpm.  This also builds all the other kernel
rpms.  RedHat has modified the kernel.spec to not build the .i386 kernels
by default.  I really suggest that you modify the kernel.spec file and
reenable this and build your own kernel out of this.  In the end you will
get a rpm(alot of rpms).  This is better than just a kernel binary.

If your problem is not kernel related then all of this is mute.

Note that neither RedHat nor us support i386/i486.
