R.I.P. :)
(not that they would have worked with libata in the first place)
How did they work anyway? By specifying geometry manually to the
driver? I think we can do that. We just need another cute HORKAGE.
ATA_HORKAGE_NO_IDENITFY and some massaging around EH to handle it.
Heh... That's gonna be a silly but fun project. :-)

Geometry from CMOS, BIOS, partition table, or kernel command line.
But I haven't owned one for perhaps 15 years or more,
and they really are NOT WORTH IT in libata -- all of those
nice little ata_id_* macros would be affected.
If one did want to do it, I think the best approach would be to
generate a fake drive ID block, and populate it with suitably
pre-ATA1 era default values. Then the rest of libata would not
require modifications.
