Are you not running a CentOS kernel? That module should be available.
I have a *stock* CentOS 6 kernel: 2.6.32-696.28.1.el6.x86_64. And no, that module is not in a CentOS Plus kernel either.
The UUID of the VFAT volume (not the mirror) would be used in the EFI boot entry. Boot off a rescue disk when the new disk is installed and add an additional boot entry for the new disk. It will reflect the UUID of the EFI partition on the new disk. Run ‘blkid’ to compare.
The UUID in the BIOS is NOT VFAT volume. It is something completely different. I have no clue what it is -- it does not correspond to anything I can find.
