Description of problem:

When plugging a USB mass storage device (in this case an iRiver
portable hard drive MP3 player), it is correctly auto-mounted, but the
 SElinux MAC prevents write access to the drive.  Files could be read
and deleted, but not created or modified.  This is on a fresh install
of FC3test3.

Version-Release number of selected component (if applicable):

1.17.24-2

How reproducible:

Every time.

Steps to Reproduce:
1.  Log into gnome desktop
2.  plug USB hard drive with vfat partition into usb port
3.  attempt to create files on the drive.
  
Actual results:

permission denied for all users (including root and the owner of the
drive)

Expected results:

Drive should be writable by user logged into console when drive is
inserted.

Additional info:

When unmounted from the desktop and mounted by hand by the root user,
write access is possible.  Booting with selinux=0 also "fixes" the
problem.
