Running something like this should work (not sure how you'd put
it in a startup).  And it would have the advantage of notifying
you at the right time, to the second (or whatever resolution
sleep uses).  I've NO idea, though, how much load "sleep" causes
(IIRC, it isn't much)

sleep $(expr $(( 60 * 60 * 24 * 365 )) - $(cut -d. -f1 < /proc/uptime)) ; /usr/bin/uptime | mail -s "One year uptime" user at localhost
