This turns out to be uninteresting then.  I think you have to configure
something specially to get console messages in dmesg, but I get then in
console.log, which also requires special configuration (turn this on in
syslog.conf).

In my configuration, vidcontrol only does ioctls in rc.d, so there are
no escape sequences for vidcontrol in console.log, and only 1 error
message (for changing the font to a syscons font).  There should be
more failures, but some ioctls are null instead of working.
"vidcontrol show >/dev/console" works to show the colors and also to
show that escape sequences end up in console.log.
