Well, yes.  It's not possible to log stuff (ie. via syslog) that happens
before /dev is mounted (so there's access to /dev/log and /dev/klog) --
but that happens really early once the system goes multiuser.  There is
some bufferring, so you'll see messages logged in sequence /before/
syslogd itself starts up.

See /var/run/dmesg.boot for the stuff the kernel prints out directly.
