The /preload partition is (hopefully) not used by Replicant.
On my Galaxy Note II (GT-N7100) it contains several files:
An audio file (Over_the_horizon.mp3) a video file
(Wonders_of_Nature.mp4), and what looks like examples files
for the "S Note" nonfree application.
On my Galaxy SII (GT-I9100) it instead contains some APK and
application data.
So it's still a good idea not to mount that partition at all.
In addition, if for some reason it becomes corrupted, Replicant
will fails to boot very early on.
