Well, it's easy : it depends of the user you mount your VFAT partition with.
Look at this example (on ext2) :

nexus6:~$ ls -l toto
-rwxrwxrwx   1 ulmer    users           0 Jan 29 20:53 toto
nexus6:~$ su otheruser
Password:
nexus6:/home/ulmer$ ls -l toto
-rwxrwxrwx   1 ulmer    users           0 Jan 29 20:53 toto
nexus6:/home/ulmer$ chmod o-x toto 
chmod: toto: Operation not permitted

So if like me, you had your VFAT partition mounted R/W for everybody on the
system (or for people from a particular group) but with owner = root, you
will have the chmod problem (I was bitten by it once while playing Baldur's
Gate).

This bug is really painful for multi-user systems... In my case, I fixed it
to have the VFAT files mounted with me as the owner :-)
