I suspect you are correct - I'm beginning to suspect you have a 16-bit
PCMCIA bus which would complicate things (and I don't know much about
them, or self-mutilation)

Perhaps, I wouldn't put too much stock in udev (it's like Wikipedia).

Hence my request for the output of:-
grub> lspci

Could you take a picture of the actual output, post it somewhere, and
post a link?
..or type in the information.
Also the lspci from a Live CD (if possible).
If it's lengthy put the info on paste.debian.net

I don't know what modules are loaded by your system, so I don't know
what capabilities your GRUB has.
If you look at /boot/grub/grub.cfg you'll see modules loaded (insmod).
/boot/grub/command.lst will show you what commands are available to
GRUB. The starred entries to the left of the : are the commands, to the
right of the : are the modules they come from.
Adding further modules is simple, building new modules is slightly less
so. If a capability is missing from your kernel, and not supplied as a
module in your initrd it may be possible to add it as a GRUB modules.
I'd need to know your PCMCIA hardware to know more.
