Mount fails with "unknown filesystem type 'jfs'" even if a new filesystem is created with jfs_mkfs on this system and jfs_fsck reports it as clean.  So, I can create the jfs filesystem, and validate it is good, I just can't mount and use it.

If the system doesn't boot you need to create a new initrd. If the mounts don't 
work, you need to load the jfs module before mount. I assume the way you will do 
that is by the proper entry in /etc/modprobe.d directory.

Maintainers: why doesn't the module get loaded on demand like other f/s types? 
Because he "moved to FC12" (I assume an upgrade) rather than a default install?
