Kevin,

I'm not doubting anything you say here, I'm just trying to 
learn. Here's some output from the kernel.log at boot-time on
one of my systems. Is it that the kernel will inspect a map
file if it exists, but for no reason?

I guess I'm confused as to why, if the System.map file is not
needed, does the kernel look at it?

############# Log file snippet ################

/boot/System.map-2.6.4.

modules not enabled.
