Hmm, no. More like the fdc's all became "IP" ("intellectual property
module") verilog/vhdl to be added as an extra device in ASIC "super-io"
designs.
It is quite possible that one such base fdc "IP" module design used by
lots of such super-io ASICs cut corners (or someone screwed it up, no
way to know for sure), and did not implement the full spec, or did it
badly.
I would be hard pressed to tell you which super-io parts do have a
non-joke fdc. The only thing I have that uses them is a MSX2+, and it
has its own discrete FDC that has been working flawlessly for 25 years.

Are you sure this isn't a kernel driver issue? The Linux floppy driver
doesn't see much love, and the people who *do* still use it are *not*
good at helping. We don't see much posts of the "I will help" sort in
LKML.

While true, it won't help boot an old x86 box :p You'd have better luck
with PXE-based network boot, or something. Should be easy to find an
old NIC with a PXE boot ROM for US$ 10 or so on ebay, if your old box
lacks one :p
