That would probably be fine on a dedicated embedded system, where you
never plan to change the kernel once it does what you want. But I'm
planning to continue to run Debian on this device, and will want to
update the kernel along with the rest of the packages on the system on
a regular basis.

I don't think I need to. The --append option to kexec seems to work
fine. (See the boot transcript in the thread I referenced -- the
command line is being passed correctly.)

Not yet. All I've done so far is a minimal kernel config and a
simple-minded rootfs with busybox and kexec-tools. I'll write a HOWTO
if I can ever get it actually working.
