I just got the netbsd10.patched kernel to boot on my IIsi in
multiuser by turning off serial console and changing /etc/ttys.
When a user other than root tries to run ps, I get an error 
like '/dev/mem: permission denied', and ps aborts. /dev/mem
is set rw-r-----.. should I just make it world readable, or
is this a symptom of something else?
