As you have another SCSI controller, the usual 

alias scsi_hostadapter aha152x
options aha152x aha152x=0x340,9

probably won't work. However, if the driver of your on-board SCSI
controller is compiled into the kernel or loaded manually, thid might
be a solution.

Otherwise I would just put your modprobe line into a start-up file
(something like /etc/init.d/boot.local, I don't know the exact file
for RedHat). Maybe RedHat has also a file for the modules to load at
startup. On a Debian system, it's called "/etc/modules".

Which version of SANE do you use?
"ping barcelona" and "ping radich" works on the linux host?

That's ok. Press some keys, the connection should be closed after some
time. You should also find a note about that in syslog:

May  5 14:22:15 hmg1 saned[2170]: init: bad status=12 or procnum=1734763623 
May  5 14:22:15 hmg1 saned[2170]: quit: exiting

Edit /etc/sane.d/net.conf and add "localhost". Try "scanimage -L"
again. There should be additional entries like

device `net:localhost:microtek:/dev/sge' is a Microtek ScanMaker E3 flatbed scanner

Now try "barcelona" instead of "localhost" in net.conf. Does this also

Are there any entries in syslog?

You can start saned in debugg mode. Disable it in xinetd.conf and
start it manually (saned -d5). It should print more verbose messages
now. In this mode you must restart it for every connection.
