mount -f -v /dev/{insert device} /{insert mount point}

the -f flag tells mount to do everything _except_ the actual mount. Since
mount will automatically read the superblock to determine the filesystem
type this will differentiate between ext2 and ext3 - Note that the ONLY
real difference between ext2 and ext3 is the existance of the journal
file. No journal file = no mount ext3... 'k?
