I believe in my particular case, I'd want to use the scsi.device that is installed when the system boots up with the Fast ATA MK-VIII, correct?

Yes, the FastATA driver is all you need, any updates to scsi.device isn't relevant under normal use. If you'd like large hard drive support from cold boot (with a custom rom or whatever) then I'd guess you'd still be able to achieve that with an updated scsi.device in rom, but obviously the FastATA driver will still need to be run, or your FastATA card it will just act the same as the onboard IDE (PIO 0 and the one IDE port).
