Are you booting the new kernel from "/vmunix.new", or something like that?
If so, that's your problem.

Commands like "netstat", "ps", "pstat", etc., need to muck around in /dev/kmem,
and they need to know offsets into kernel space to do that.  They find these
offsets in the system namelist, which, by default, is in "/vmunix".  Most of
these commands also have options to tell them the name of the running kernel,
if it isn't "/vmunix".
