Is there any explanation/history behind the name of the command
dmesg (which prints out some kernel messages)?
dmesg - system diagnostic messages Dmesg looks in a system buffer for recent kernel diagnostic messages and reproduces them on the standard output

dmesg command just stands for display messages. The FreeBSD manpages seem to share this view:
dmesg -- display the system message buffer
According to Wikipedia,
dmesg is "display message or driver message"
