Forgot to mention that it isn't perfect. I believe the limitations
described in http://www.freebsd.org/releases/5.3R/relnotes-i386.html
are still true:
|The MSDOSFS_LARGE kernel option has been added to support FAT32 file
|systems bigger than 128GB. This option is disabled by default. It uses
|at least 32 bytes of kernel memory for each file on disk; furthermore
|it is only safe to use in certain controlled situations, such as
|read-only mount with less than 1 million files and so on. Exporting
|these large file systems over NFS is not supported.
