Things, especially Midnight Commander, whine about chmod/chown on a FAT partition

Ever have cp warn you that chmod/chown on a FAT partition failed? Not too annoying. But when Midnight Commander (and by extension, the Gnome File Manager, gmc) gets this error, it pops up a box. For each file. I hate that. To get rid of this obnoxious behaviour, mount your FAT so that it doesn't display the error by setting the 'quiet' flag.
