I can only speak to Intel, as I have yet to get Hardhat
booted.  Generally, I start with the kernel source rather than
an rpm.  Of course, upon install of a new dist, you start with
the dist's packaged version.  But I would replace that asap,
tailoring it based upon what you need.

RedHat separates the kernel into at least two rpms, though
kernel-headers.rpm is most likely a subset of the kernel-src.rpm,
consisting of only include files used for compiling other sources.

Get the 'real' kernel source.  Unpack it in /usr/src as linux/.
cd /usr/include; rm asm linux; ln -s /usr/src/linux/include/linux;
ln -s /usr/src/linux/include/asm; cd /usr/src/linux; read ;)

Menuconfig has quite a bit of online help, plus the Documentation
tree will help you become familiar with the available options.
make xconfig is nice as well, especially for browsing and immediate
recognition of dependencies that some choices enforce.  Other than
that, the Linux Kernel HOWTO, which I guess you have read.

Note that the completed configuration ends up in .config in the
top level of the source tree after make config, make menuconfig,
or make xconfig.  I like to keep a copy of this outside the
tree so that I can maintain some consistency from kernel to
kernel, rather than start over with each new src tree.

After running make (menu/x/)config, always do make dep;make clean;
I then do make zImage;make modules;make modules_install
