As far existing files on the disk, they will only be writable by the  
UID that created them (or GID if group has write permissions) because  
ext2/ext3 preserves permissions as a filesystem - fat32 doesn't.

As root, create a directory on the ext3 partition, and give rwx to your  
user. I bet your user can then rwx in that directory, no matter who  
mounts it. That's probably what you need to do - create directories on  
it owned by the users that are allowed to use it. Then those users can  
use it. Or you could create a directory on it with 777 permissions -  
like /tmp is (I think you also would want to set the sticky but, not  
positive)
