I have an eSATA external hard drive case. I want to hotplug / unplug

My system is Fedora 11.
I added an external eSATA port on my desktop computer by adding a bracket
(with an internal cable connected to one of the ordinary SATA sockets on
the motherboard.)
The SATA controller is an intel ICH9R. To make hotplug work, I needed
to go the computer's BIOS and change the SATA mode to AHCI (it was
IDE).
I can now hotplug the drive.
I cannot unplug the drive. If I tell the system to eject the drive,
it complains:
# eject /dev/sdi
eject: device "/dev/sdi" doesn't have a removable or hotpluggable flag
# cat /sys/block/sdi/removable
0
(I don't know where or what a hotpluggable flag is.)
I guess that makes sense: the system doesn't know that I added an
eSATA bracket.
What are the reasonable ways to tell the system that that SATA port is
an eSATA port and should allow for hotplugging/unplugging?
My guess is some kind of HAL rule but I'm not an initiate. Maybe
something in here would work:

Surely lots of people have already encountered this issue. If so,
there ought to be a non-wizard way to handle it.
Hi
I have used hotplug hard drives for some time but never used eject
Try to sort it out as root and then move on to a normal user
What does mount show when the disk is plugged in?
It should be showing /dev/sdix I believe not /dev/sdi
umount should be working for root but not for a normal user
Brute force enabling of a normal user to mount a hotplug ext disk
For F11
I edited /etc/PolicyKit/PolicyKit.conf to permit "everybody" to mount
<config version="0.1">
<match action="org.freedesktop.hal.storage.*">
<return result="yes"/>
</match>
</config>
or even worse
nedit /etc/PolicyKit/PolicyKit.conf Let root and ja do anything !!!!
<config version="0.1">
<match user="root|ja">
<return result="yes"/>
</match>
</config>
These hacks have changed for F12 !
I am using KDM and XFCE and gnome is installed so what is controlling
udev/hal type things is a mystery to me !
With the hacks above for a normal user the disks get mounted and the
Thunar file manager is opened automatically
However I use pcmanfm to unmount external eSATA disk partitions as they
are all shown in the file manager side panel
