Dear Steve,

Sounds a bit like my problems on Mandrake 9.0/9.1. I found that 
rmmod-ing the iee1394 and ohci1394 modules, then re-inserting was 
necessary before modprobing sbp2. You might also find gscanbus useful 
(it requires raw1394). Another possibility is that you try it with 
Knoppix (which usually gets things right), and then look at the Knoppix 
/etc to see what they've done.

Best wishes

Richard
