It is complete, but linux-2.4.21-selected-ac-bits.patch disabled it. I
have no idea for whatever reason. 
Here is how it worked for me:

Install the source-rpm
# rpm -i kernel-2.4.21-9.0.1.ES.src.rpm
# cd /usr/src/redhat
Edit SPEC/kernel-2.4.spec and disable patch 5410, 5411 and 5412.
Add a new patch to the specfile

# echo <<EOF > SOURCES/linux-2.4.21-config-acpi.patch
diff -Nur linux-2.4.21/arch/i386/config.in

and enable it in your specfile somewhere

Patch23456: linux-2.4.21-config-acpi.patch

and also in the %setup section

%patch23456 -p1

Do a 

# rpmbuild -bp kernel-2.4.spec

copy the configuration file for the architecture you want to build into
BUILD/kernel-2.4.21/linux-2.4.21, for instance for a dual-Pentium
machine

# cp SOURCES/kernel-2.4.21-i686-smp.conf \
    BUILD/kernel-2.4.21/linux-2.4.21/.config
# pushd ./
# cd BUILD/kernel-2.4.21/linux-2.4.21/
# make menuconfig
In 'Gerenal settings' add ACPI stuff

Copy config back to the src-directory
# popd
# cp BUILD/kernel-2.4.21/linux-2.4.21/.config \
      SOURCES/kernel-2.4.21-i686-smp.conf

Build the kernel
# rpmbuild -ba --target i686 kernel-2.4.spec

Hint: by setting buildup, buildsmp, buildBOOT, buildhugemem, buildsource
to 0 you can rstrict to build of a kernel to only what you need.

If you have a laptop, use as configuration
SOURCES/kernel-2.4.21-i686.conf, enable buildup but disable all the
others.
