Oh. ps doesn't use /dev/kmem.
Look at a ktrace of it; it works just as it should. /tmp/ps
auwwx prints what it should and the ktrace output shows it opens
the processes whose memory it can read (as ``nobody'' I could
read httpd processes, my ksh process and my ps process) and
errors for those it cannot:
8290 ps CALL __sysctl(0xbfbfc944,0x4,0xbfbfc954,0xbfbfc940,0,0)
8290 ps RET __sysctl 0
8290 ps CALL open(0xbfbfc878,0,0)
8290 ps NAMI "/proc/7997/mem"
8290 ps RET open -1 errno 13 Permission denied
8290 ps CALL close(0xffffffff)
8290 ps RET close -1 errno 9 Bad file descriptor
