The FAT32 file system doesn't know Linux (Unix) permissions. You could 
only change the permissions with the mount option "umask=022" (I think 
this would be the right one, but I didn't try it myself) when mounting 
the partition. Or maybe you want the dmask mount option? See "man 8 
mount" for details. Anyway, it is a setting available only for the 
entire partition, not individual directory trees and on the next machine 
the permissions are gone. If you really need Linux permissions, use a 
Linux file system like ext2.
