yes, it's most likely a problem in the Linux SCSI system. To look for 
SCSI scanners, sane-find-scanner reads /proc/scsi/scsi, and the contents 
of this proc file is "managed" by the SCSI system of the kernel.

Are you sure that the sym/ncr53c8xx module is indeed loaded? And if it 
loaded, do you get any error messages in /var/log/messages?

The sym/ncr53c8xx drivers offer many parameters; perhaps it helps to 
play with some of them. The file
<kernel source dir>/drivers/scsi/README.ncr53c8xx describes these 
parameters quite detailed.
