I guess I sort of thought there was some trick way to just compile a
module and not do all the linking and grinding of `make' against the

Unless you've done 'make clean' previously, 'make' will only compile
required files based on changes you've made to your config. My laptop
runs a monolithic kernel with very few modules (PCMCIA and USB
hotplugged stuff), but as long as I'm not changing versions, adding or
removing features usually only involves compiling a few source files and
linking the bzImage.
If you just want to build new modules and haven't made any changes to
the actual kernel, 'make' can be left out since the bzImage doesn't need
rebuilding - 'make modules modules_install' will be sufficient to build
and install your newly selected modules.
If you've run 'make clean', which removes all previously compiled
objects, a monolithic kernel will have to be rebuilt from scratch - but
once again, running only 'make modules modules_install' will rebuild all
your modules but leave the kernel itself alone.
HTH.
