>Description:
when using dmesg to check what happened at boot time,
I got "dmesg: incorrect magic number".
I mistook this first, as having corrupted my dmesg by accident,
but people from de-bsd-questions told me, that my kernel was
older than my dmsg binary, simply.
>How-To-Repeat:
>Fix:
I suggest this patch to clarify things (or put some hint on the man page)
