I have two F11 machines that hotplug eSATA OK
In the back of my mind I seem to remember you have to set the BIOS to
SATA mode AHCI

I also hack PolicyKit so normal user can mount "fixed" disks

nedit /etc/PolicyKit/PolicyKit.conf so ja can mount disks OR Use
Xfce/Settings/Authorisations
                                                                        
<config
version="0.1">                                                                                                                                               
<match
action="org.freedesktop.hal.storage.*">                                                                                                                       
    <return
result="yes"/>                                                                                                                                           
</match>                                                                                                                                                             
</config> 

I use pcmanfm as file manager when I'm playing with eSATA
as all disks (USB and eSATA) are shown and can be mounted/unmounted
Neither dolphin or thunar get it quite right yet
