Permissions can and will change on the mount point when you mount a 
device depending on who you permit to mount it.  For example, if you 
permit any user to mount the device, you'll see that the mount point 
will be owned by that user when that user mounts it.  Here is an example 
for my memory stick device on my laptop:


rhws/home/esoteric> ls /mnt/memstick
ls: /mnt/memstick: Permission denied
rhws/home/esoteric> mount /mnt/memstick
rhws/home/esoteric> ls -ld /mnt/memstick
drwxr-xr-x    3 esoteric users       16384 Dec 31  1969 /mnt/memstick

/etc/fstab entry for this device:

/dev/sda1 /mnt/memstick vfat noauto,user,exec 0 0

Note the user option in the entry.

If I unmount it, then su to root and list the device I get:

root at rhws/home/esoteric> ls -ld /mnt/memstick
drwx------    2 root     root         4096 May 12 13:59 /mnt/memstick
