I added
   fuse_enable="YES"
to /boot/loader.conf.local
and
   fusefs_enable="YES"
in /etc/rc.conf
Then rebooted.

Should "fuse" show up in a sysctl -a?
# sysctl -a | grep -i fuse
shows nothing

# mount.exfat -d -o ro /dev/da0s1 /mnt/memstick
FUSE exfat 1.2.8
fuse: failed to open fuse device: No such file or directory
# dumpexfat /dev/da0s1

If I put the SD card in a win7 system it says it is an exFAT filesys,
so at least we're on the right track.
