Because I learned something by doing it.

I'm not sure it does:

$ last reboot
wtmp begins Fri Jun  1 08:31:38 EDT 2012
$ uptime
  9:30PM  up 529 days,  8:25, 4 users, load averages: 0.02, 0.18, 0.17

...and even so, would it show a cold boot, or only a reboot?

I'll credit Doug Hardie with the best solution:
$ ls -l /var/run/dmesg.boot
-rw-r--r--  1 root  wheel  7248 Dec 26  2010 /var/run/dmesg.boot
