And just to clarify this further.  When "mod -S [directory]" is entered,
the search will be made starting from [directory].  In other words,
it will not immediately append "/lib/modules" and "/usr/lib/debug/lib/modules"
onto [directory].  It's just that that's where they'll be found
if the double-rpm2cpio were done.  

Conceivably you could just dump all the .ko and .ko.debug files into
the one flat [directory], and it will find them right away.
