It's not port-mac68k specific.  You can, if you build your own kernel,
have the SCSI IDs hardwired.

The BSD method is more flexible with multiple scsi busses, though.  How
would linux number with two busses?  Or with a device that has multiple
disks on multiple luns of one target (like some old ESDI interfaces did,
I think)?

It sounds like you might want to hardwire the scsi IDs in your kernel.
That's easy to do.  Add likes like the following to your configuration
file, reconfig, and rebuild:
sd0	at scsibus? target 0 lun ?
sd1	at scsibus? target 1 lun ?
