At the risk of making people testy, this is the easy part.  There is
lots of stuff about how modules save memory.  There is lots of
information about how they are used in initrd.

I looked at them in /lib/modules/<kernel>/* (various and random files)
they *seem* to give addresses.  Is that what a module does?  Load
addresses for devices and/or device drivers so that the kernel can find

To clarify, the question is not to challenge the usefulness of modules
but to uncover how they work visa vie drivers.  Or are they the same
thing as a driver?  Stuff I have read, sometimes seems sloppy about
distinguishing between drivers and modules if there is, in fact, a
