: I don't think you understand what I'm saying. For most modules, it is not 
: actually necessary to pre-load them at all. For example, I have cd9660 as a 
: module, it's not compiled into my kernel. When I mount a cd9660 file system 
: the kernel module is automatically loaded. There is no need to pre-load it. 
: The same is true of (most) modules that create devices, such as ndis.

: I don't know the specifics of the sound module, I compile it into my kernel. 
: However, as you pointed out in the rare case that it's necessary to actually 
: pre-load a kernel module (such as agp), we have a mechanism for that in 
: loader.conf already. I don't think that adding that code to rc.subr is a 
: useful exercise, and in fact I would oppose it as needless duplication of 
: effort.

It is also better to have the boot loader load modules that you are
going to load right away anyway.  Having it in rc is insane.
