AFAICT 'mount' displays (more or less) the contents of /etc/mtab, which may under certain conditions not be up-to-date. /proc/mounts is more accurate, but I doubt in your case this is an issue. As for the options in /etc/fstab being applied or not, if you read the thread on debian-devel, it was pointed out that Debian's initscript(s) will remount the root fs with the options from /etc/fstab, it's just that some options can not be changed on a *remount*. For those particular options you will have to use either rootflags or tune2fs.
