You should only need the last kldload call.  Any other magic is probably
left over from times when kldload didn't work properly.

The synopsis for kldload(2) should be "find and load the named kernel
module".

In essence, it takes either a module name and searches the "right"
places for it, or it takes a fully-qualified pathname and loads
exactly that module.  That's all; anything else is a bug in the
implementation and should be fixed.
