In all 2.4 versions I've tested, (the most recent of which are
2.4.20-pre4-ac1 and 2.4.20-pre8), ide-scsi, sbp2 and usb-storage all
use scsi host id 0.  Eg (w/ just ide-scsi and sbp2):

:; cat /proc/scsi/scsi 
Attached devices: 
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: Maxtor   Model: 1394 storage     Rev: v1.2
  Type:   Direct-Access                    ANSI SCSI revision: 06
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: SONY     Model: CD-RW  CRX810E   Rev: 1.4c
  Type:   CD-ROM                           ANSI SCSI revision: 02

This causes problems at lest for sg:

I can't test 2.5 on this box, as /home, /opt, /tmp, /usr, /var and
swap are all in LVM1.

What does it take to get the host/channel/id/lun tuples to increment
the host value each time a releted module is inserted?
