That cannot be true. One can simply concatenate stage1 and stage2
onto a floppy disk and use that as a boot floppy. No "menu.lst" is
required.

GRUB will name the first hard drive it sees (hd0), the second one
(hd1), and so on. I don't see where a "menu.lst" file must come into
the picture.

That is the Linux <=> GRUB correspondence that I can determine from
running the "grub" command under Linux. My BIOS boot order is to look
first at my floopy drive and then at "C:", which ends up being
/dev/sda thanks to some help from my SCSI controller's BIOS.

I have no such file. Nor is any such file required when all I'm
trying to do is get the geometry of a GRUB device.

*I* am not mapping anything. GRUB is selecting mappings
automatically. When run as a command under Linux, GRUB maps /dev/sda
to (hd1), /dev/sdb to (hd2), and /dev/hdc to (hd0). When run as a
boot loader, GRUB appears to map /dev/sda to (hd0), /dev/sdb to (hd1),
and does not present any device corresponding to my IDE drive.
But that's all irrelevant. The order doesn't matter. I couldn't care
less what the order is. A command like "geometry (hd0)" should
produce some kind of meaningful output. I don't care if (hd0) is my
first SCSI disk, my second SCSI disk, or my IDE disk. It doesn't
*matter*. No matter which disk it is, "geometry (hd0)" should
describe its geometry. But when GRUB is run as a boot loader,
commands like that just hang outright.
