I've just booted into VL6 Light on the same computer and here the Adaptec driver is loaded and sane-fine-scanner finds the scanner.
aha152x lines from dmesg:
Loading iSCSI transport class v2.0-870.

As you see, the scanner itself (Scanner 600) is identified. The lines I thought were signs of trouble in dmesg for VL6 Standard are not; they're the same in dmesg for VL6 Light. However, aha152x is not found and the scanner is not identified.
sane-find-scanner reports this in Light:
found SCSI scanner " Scanner 600 1.80" at /dev/sg0
# Your SCSI scanner was detected. It may or may not be supported by SANE. Try
# scanimage -L and read the backend's manpage.
same computer, same SCSI card, same video driver (xorg's radeon), same scanner, same append in lilo.conf. Why isn't it working in Standard?
This is the second weird problem I have with Standard on this computer. I can't get Flash working with Opera 9.04. It doesn't see the plugin at all. Flash works fine with Opera in Light. I've tried just about everything in Standard: removed Opera completely and reinstalled the package; compared the settings and files in Light with those in Standard--they're the same; reinstalled Flash; renamed ~/.opera and had Opera create a new one. Opera works with Flash on my other VL6 Standard computers and with VL6 Light on this computer. I'm stumped.
