The last three lines correspond to /dev/sdb which is where the new
64-bit Fedora is.

I'm not sure what to make of the above, but sfdisk says to use GNU
parted, so:

The above clearly shows that there is SOME kind of LVM information in
/dev/sdc, but again I don't know why the system doesn't seem to deal
with it as I would expect.

Given all the above information, there does not seem to be anything like
/dev/dm-0 that corresponds to /dev/sdc. Again I'm at a loss.

I suspect you're right, but I don't know how to do any of that.
