Even better would be to add a stage in front of the fall-back, which queries the BIOS (from kernel startup code) for translation info on ALL drives.
It doesn't work.
I wrote the code and asked people to test it.
So many BIOS quirks.
(Numbering of drives depends on setup options, and on whether there are SCSI disks mentioned in the BIOS setup, there are off-by-one errors in several BIOSes, several versions of Phoenix extensions are implemented etc. It is really not worth trying to go this way. It fails.)
No, geometry does not exist, and also BIOS drivers have come to the same conclusion.
Since nothing depends on it, there is no reason to want any geometry in particular.
