The mounting is controlled by HAL. But I do not think what you are
after can be done. I have not seen any option when mounting an
ext2/3 file system that will allow you to ignore or remap UIDs and
GIDs. You may want to consider remapping the user/group IDs on your
Fedora system to match the drive, especially if you are using it to
move data between systems. Check out the usermod command.
