See http://www.centos.org/modules/newbb/viewtopic.php?topic_id=19694 my guess is they detect specific RHEL5 versions and the current truecrypt code is choking on the updated rhel5 kernels, not recognizing the latest, and giving you a faairly bogus error message... You can either go back to a earlier Centos5 kernel, or hope Truecrypt fixes their stuff. Xen could also be an issue, I have no idea how this works with Xen.
