You'd need some tamper-proof setup to record all reboots (and better yet, 
all other system activity). This usually means some kind of hardware, like 
a blackbox used in airplanes. A less paranoid version of this could be a 
remote syslog server, recording reboots even if a local logfile has been 
modified/erased.
