Indeed.  I found a machine running linux 2.6.0-test8:
 # uname -r
 2.6.0-test8
 # ls -l /tmp/testfile 
 -r--------    1 root     root           49 Dec  8 11:48 /tmp/testfile
 # (su -c cat nobody) </tmp/testfile 
 foo bar
 #

fine, but:
 # ls -l /proc/kmsg 
 -r--------    1 root     root            0 Nov 24 10:00 /proc/kmsg
 # (su -c cat nobody) </proc/kmsg 
 cat: -: Operation not permitted
 #

with kernel 2.4:
 # uname -r 
 2.4.22
 # (su -c cat nobody) </proc/kmsg 

it works fine.

I'm curious if this change to the proc file-system is intended.
