Relax. It is not so bad. Here is what you do:
a. Install your core system, avoiding any single file system (slice)
larger than about 4GB.
b. Boot the system and use disklabel -e, etc. to create the really large
filesystems.
c. Modify /etc/rc as per my previous post.
d. Call me if there are any more problems.

Yes. Fsck on such a filesystem is a bit slower.
Not too many people actually tested the filesystem code, overflowing
32bit addresses.
Backup of such a partition may be interesting too.
