details about EOL (of FreeBSD 5.4) ?

[albi]

i'm running 5.4 on a few servers, and i wondered till when
security-updates will be available

http://www.freebsd.org/security/ says that the EOL is estimated may 31
2006, but does that also mean no more security-updates for 5.4 ?

i have no problem with doing a reinstall with the brand new 6.1 (or is
the upgrade-jump from 5.4 to 6.1 no problem at all ?) , but i just like
to get an idea when that would be really needed :)
