If it were static, I could.  This is for analyzing crash dumps that
have been created on other systems.

I gather that both of these are really the same in that the first case
simply appends each input line to an empty string.  This is exactly what
I was asking for, plus a little bit.  Since I wasn't expecting the
"mod -s < input" formulation, I likely just didn't stumble over it.

Anyway, since I won't know in advance which modules are loaded;
and once I do know which ones they are, I won't know where they are;
I will need to use a feedback loop.  crash must tell a hunt-it-down
script which modules are needed, then that script tells crash where
to load up the .ko files.  Perfect.  Thank you so much!!
