there is a way where a non-root user cannot see dmesg output.  CRS
syndrome has clouded my memory.  Take a look at the klogd man page.  I
believe I wrote about how to do this in my book (or maybe not, but it
is possible to do this).  Something to do with empyting the ring
buffer,  perhaps?

Look in /var/log/kern.log (or wherever /etc/syslog.conf logs kernel
messages), they should still be there (the messages from the kernel).
