Another possibility is to use an internal <-> external Adapter on the
SE cable, but you have to be carefull about the max cable length. 
BTW, some scanners do not support scsi-disconnect and will stop the
scsi bus while scanning (Mustek ie.) so a dedicated controller for the
scanner might be a good idea anyway .
