This is a perfectly valid decision. At work, I have systems running
software (not FreeBSD) that is getting close to 10 years old for
similar reasons.

In general, support of your systems will comprise some combination of
in-house support, vendor (eg FreeBSD Project) support and 3rd-party
(eg consultant) support. Over time, this mix will change as the
vendor reduces the level of support they provide for a given software
version. You need to take this into account when making a decision to
stay at some version X: As vendor support is reduced then your in-
house and 3rd-party support effort will increase. At some point, the
cost/effort involved in staying at version X outweighs the cost of
migrating to a newer "supported" version of the software.

The FreeBSD SO has advised that 5.x will receive security updates
until 31 May 2008. This gives you 15 months to either migrate to
6.x (or 7.x) or arrange alternative security support.
