These are great examples of why you want to build from a source RPM. 

For hardware compatibility, if the machine won't _boot_ without a special
kernel, you're clearly not building on that machine itself. So you want some
nice way of getting the specialized kernel onto the system -- sounds exactly
like a job for an RPM _package_. 

If you're removing kernel features for security, having a new package with
the parts you don't want just _gone_ seems much cleaner than having the old
kernel managed by RPM with a new kernel with some missing parts smeared on
top of it.

For incremental changes, keep the same original source RPM, and add in your
tiny little patch -- without mucking with the pristine original. (RPM is
great for this.) You can do this over and over, and the RPM package release
numbers and changelog provide a convenient (and standardized) way to
document the differences.

This all becomes exponentially more true if you have more than one machine
to deal with, but it's true on one system too.
