John,

Thanks for the confirmation.

That's what I had always assumed. I, too, have used that method for
years and failed to see that it made any difference.

I have now built a new kernel (with modules) from the sources back on
December and I am no longer getting the warnings about the module being
newer than the linker.hints file. I am totally baffled as to what
triggered this as I did confirm that the modules and the linker.hints
file were created at the same time (modulo 1 minute) and I don't see
how this could have gotten messed up. 

In any case, Thanks for all of the comments on booting different
kernels. I do this quite often and I'm now pretty sure that I am
doing the right things(TM).
