the SCSI system detects the scanner.

this looks indeed a bit strange, but there are some ways to parallelize
the init scripts; perhaps RH 8 uses such a technique.

That's related to Firewire stuff; it probably does affects ypur scanner

It's a scsi scanner, not a parallel port scanner, so why the parport line?

symlink to /dev/sg1, but xsane still pops up a dialog box with "xsane:
no devices available".
If /dev/sgb pointed to /sg1, that was indeed an error.

Don't forget to look, which group is set for /dev/sg1. Generally,
ordinary users don't belong to the group assigned to SG device files.

A possible reason is that the sg module is not loaded. Try a "modprobe sg"
