I worked out the issue with the kernel modules and symbol
versioning conflict from my old boot floppy and new modules.

However fai still does not write the disk_var file.
It is strange.  class/S03hwdetect.source does not appear to call
disk_info and so it never writes /tmp/fai/disk_var.sh .
Now I appear to have this problem with an IDE-only unit.
Hmmm, /proc/partitions was empty when S03hwdetect.source ran.
But setup_harddisks found disk info in /proc/partitions.
Apparently this IDE bus or this disk does not activate
unless polled.  I added "sfdisk -g -q" to the top of
S03hwdetect.source, and this filled out /proc/partitions.
Maybe this will work with the SCSI unit, too.
