Giusto, e per chiunque dovesse incappare in simili intoppi,
a titolo divulgativo mi permetto di riportare qui quanto
sinora provato grazie all'aiuto del gentile Pieter, in modo
da rendere il problema noto e contribuire anche minimamente
a un'eventuale 'casistica'; spero di fare cosa gradita.
 
in attesa e nella speranza di risolvere, un grosso GRAZIE a
tutti voi per la disponibilità.  :)

Ciao,
P.Domenico.

at today and above all with help of some other people
of italian m'list and Klaus, I try to workaround to solve
my issue, and verified the presence and te correct loading
of ieee1394 drivers;
 
with modprobe
 
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/eth1394.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/video1394.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/ieee1394.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/pcilynx.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/ohci1394.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/sbp2.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/raw1394.ko
/lib/modules/2.6.20-16-lowlatency/kernel/drivers/ieee1394/dv1394.ko
 
then lsmod | grep ieee1394
 
dv1394                 20828  0 
raw1394                30204  2 
ohci1394               36528  1 dv1394
ieee1394              300120  4
sbp2,dv1394,raw1394,ohci1394
 
So move to select correct driver (freebob) in the
jack's options and start jack, but he stop immediately with
this error message:
