Netstat, vmstat, and a few other tools directly grovel through the
kernel and its structures to get the data they need.  In order to do
this, they need to find the locations of various global variables (aka
symbols) in the kernel address space.  So, if you strip your kernel,
you remove all those symbols, and netstat won't work.

I know there has been work in the direction of removing that sort of
dependency.  For instance, ps used to work the same way, but it now
uses sysctl, I believe.
