note that /var/log/dmesg is just a snapshot of the output of the program 
dmesg taken after boot time.     the dmesg command dumps the current 
kernel message buffer, but I don't believe it has a live 'follow' mode.

that said, most stuff written to the kernel message buffer gets 
processed by syslog and put in /var/log/messages
