I don't see how it could have worked like you had it. Are you saying the line I gave you didn't work? All the options are in the man page:
$
man fstab
$
man mount
Most of the options are explained in the "mount" man page. The "kudzu" option is not one of the ones mentioned in the mount man page but that one is the one causing the entry to be deleted when you reboot. More on that later. The "umask=0222" is actually probably not what you want but I used it as a safe example. Since FAT/FAT32 file systems don't know anything about ownership or permissions you have to tell it at mount time what sort of access you want on the entire file system. umask=0222 would result in all files being set to r-xr-xr-x and owned by "root", that is everyone can read everything but nobody can delete or change anything. If you want full access for everyone use "umask=0000". You can also set the owner and group if you want so in combination with a umask statement you could restrict access based on users/groups. "noauto" means not to automatically mount the partition at boot time. "owner" means only the user that owns the device file (/dev/hda5 in your case) can mount the file system. "user" means any user can mount the file system. Like I said, all of these options are usually used for removable file systems (CD, floppy, zip disk, etc) and wouldn't usually be used on normal hard disk partitions.
Now on to the kudzu option. Kudzu is a hardware detection utility that runs on bootup in Red Hat. If it finds a new device like a CD-ROM drive that you installed it will add an entry automatically for that in your /etc/fstab and put "kudzu" in the options, letting kudzu know that it is allowed to manipulate that line if it needs to (including deleting it). Since you put the "kudzu" option in the fstab and kudzu doesn't know anything about any device associated with it (it didn't put it there) so it deletes the line. More on this here:
$
man updfstab
Oh, and I think if you search these forums you might find that this question has been answered a few times. Here's one example where I gave an example very much like the site you refer to came up with:
