I'm afraid there is some misunderstanding of 5 versus 5.x.

CentOS-5 is supported until 2014.  CentOS, as of this writing, is at
*point* release 5.5. If you are running "5.0" (or 5.1 or 5.2 or ...)
today, you are way behind because there have been a number of security
patches and bug fixes since 5.0.  In other words, "CentOS 5" has a
seven year support but 5.0  (or 5.1 or 5.2 or ...) is "obsolete". So,
if you install CentOS 5.5 now, you will have 4 more years of support.

Hope this clears a bit.
