I don't have FC3, so thins may not work. But if you have a file
/etc/modprobe.preload, add sg to it. I would also change your rule
to something like:
KERNEL="sg*", BUS="scsi", SYSFS{vendor}="HP*",
SYSFS{model}="C5110A*", SYMLINK="scanner%n", MODE="0666" (one line).

That way, if the scanner is ever anything besides sg0, the rule will
still work.

There should be a udev rule for this. It may also change when you
log into the console. You may need to change
/etc/security/console.perms instead.
