By reading http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.1

During the boot process you may see the message "Memory for crash kernel (0x0 to 0x0) notwithin permissible range" appear. This message comes from the new kdump infrastructure. It is a harmless message and can be safely ignored.

This is for CentOS 5.1, you can assume it's valid for 5.5 too

Does the system boot into a useful state? or does the system hang there?

If it boots into a useful state, you can either ignore the message (like I do), or you can allocate some RAM for kdump via system-config-kdump.

If the system doesn't boot, it's rather more interesting.
