The kernel isn't doing it.  A script called from installkernel (in Red Hat 9) 
calls depmod, which has to be Rusty's new depmod or it doesn't create the 
directory.  This means depmod is running against the OLD modules.

I've been bitten by this before, by the way.  I switched from an accidental 
SMP kernel to a UP kernel on my laptop, and the install complained about 
unresolved SMP symbols in the modules.  (This is how I got in the habit of 
doing make modules_install before make install, which I thought might also be 
responsible for the directory creation problem, but wasn't.  Neither creates 
the directory: depmod does).
