Right now, when installing a new system it's easiest to reboot to single 
user mode after the install and tunefs -j disable 'the filesystems' to 
disable journaling of soft updates.

If you want to accomplish this during the install, choose shell at the 
disk partitioning part and add slices and/or partitions with gpart and 
then newfs them with the appropriate options, then mount them on /mnt 
and the appropriate places beneath and continue the install by quitting 
the shell.

There are some nice entries on
Just substitute the ZFS stuff with the easier gpart and then newfs -U 
etc... then make sure the filesystems are mounted under /mnt and 
continue the installation.
I hope that I will not confuse you too much with the proposed solution 
i.e. use these resources as a guideline. Else see reboot to single user 
mode after install above and tunefs
