Mount FAT32 with full user permissions
To make FAT32 partition mounted with full permission :
sudo mount -t vfat /dev/sda11 /drive-i -o auto,user,sync,exec,uid=1000,gid=1000,dmask=027,fmask=137

Where
- vfat : File System
- /dev/sda11 : The partition to be mounted
- /drive-i : The mount point
- uid : uid associated with my username
- gid : gid associated with my username
- dmask : Directory mask for permissions (027 = 750 / drwxr-x--- in chmod)
- fmask : File mask for permissions (137 = 640 / -rw-r----- in chmod)

To get UID/GID
id

The entry in /etc/fstab will look like this...
/dev/sda11 /drive-i vfat auto,user,sync,exec,uid=1000,gid=1000,dmask=027,fmask=137 0 0

FAT32 shortnames and ALL upper-case folder
An issue was found on my environment trying to SVN checkout java project to vfat partition
folders like WEB_INF, META-INF were displayed like web-inf, meta-inf
Fix:
shortname=mixed options for vfat mount string
My /etc/fstab for vfat looks like
/dev/sda5 /media/m vfat shortname=mixed,ocharset=utf8,auto,user,sync,exec,uid=1000,gid=1000,dmask=027,fmask=137 0 0
