My Mother had some Dataframe 20s with the OMTI 3100 MFM<->SCSI
card inside.

Not without looking at a picture of the card.

AFAIK, it is just a standard, pre-SCSI-2 interface. You will *not*
be able to issue IDENT commands against it to divine the drive
geometry. You have to _know_ the heads/tracks/sectors of the MFM drive
(there are lists of those out there - I was just looking up the XT2190
today and only found 47 hits with Altavista - it's a good keyword to
use to find MFM drive lists)
The problem is probably the third-party controller. It may or may not
count on a certain set of contents of the first cylinder or two. With
the right driver disk, you could reformat that drive on a more modern
Mac, but you want data recovery.
If you can't change the SCSI id of the Hardframe, why not change the id
of the boot disk in your target Mac?
