Yes.

Yes.  Application binaries running under Linux w/NOMMU must be flat files.

I'm not sure what this has to do with your bootloader.

I'm not sure why you would want to "kill them off".  They are part of 
the auto-config approach that lets us tailor the kernel to the HW build.

Being in .config they also end up in include/linux/autoconf.h.  The 
reason you need them in .config not jsut xparameres.h is, among other 
things, that it lets the build system reason about your HW build.  Does 
the CPU have a multipler instruction?  This affects the CFLAGS you pass 
to the kernel build.  xparameters.h won't help you there.
