I manually added the following script to execute as 
/etc/rcS.d/S22sleep-for-scsi

#!/bin/sh
if (lsmod|grep eata); then
         echo waiting 5 seconds for module eata to query SCSI bus
         sleep 5
fi

The 5 second wait between module-loading and filesystem checking was 
sufficient time for the SCSI bus to be queried and device files 
/dev/sda? to be created.

As my system is not a candidate for sub-5-second boot anyway, I don't 
mind the wait if it means that the filesystems are checked before they 
are mounted (-:.
