I just bought an external HDD enclosure for my old IDE disks so I can
attack to my laptop using USB. How do I set this up? I will not always
have the same IDE disk in there when I boot (there are 3 HDD) nor will
I even have the enclosure connected to my USB port every time I boot
up. So how do I handle this? I am running 2.6.18 kernel with udev (and
no I have no clue how to write udev rules and I hope kernel developers
abandon udev foolishness in the future and return to devfs + some
extensions heh). What kernel modules will I need to load setup this
device and do I just add them to /etc/modules, run depmod -a and
reboot? And then lsmod to verify they were loaded and just plugin the
drive enclosure? Do I need create a special device for USB? I would
like /etc/fstab to automatically load the enclosure drive if it
detects it was attached on boot up.

What exactly do you want to achieve? If you don't need automounting, you
don't need to do anything at all. As soon as you plug the drive in, the
necessary module gets loaded automatically and you have to look up the
new device names in your syslog or from dmesg.

For stable device names, irrespective of the order of plugin, you need
to write udev rules. This is not as complicated as it sounds and there
are a lot of howtos on the net.

That makes it easy to write fstab entries so you can easily mount your
filesystems as a user.

Don't hold your breath.

You need to do nothing at all.

In this case you need some sort of auto mounting program. I cannot
comment on that since I don't use such a program. If you are you using
Gnome oder KDE, this is probably a complete non-issue.

If you have hal installed, you are not required to write any udev
rules, and you may use pmount mount them or use gnome-volume-manager
mount them automatically if you use gnome.

you do not need manually load any modules at all in most condintions.
