Make console driver export pointer to a table. This will make it

Of course console driver will need to cope with NULL pointer (or
initialize table to something meaningful).
Hmmm... I think this is the one thing that I have not yet tried.
If I understand correctly, I would then have to create a an EXPORT_VAR
pointer variable in the console module, and let my 'setkey' module store the
appropriate value into it.
The function to remap an input key, according to the contents of the table,
would then be a part of the console driver.
It can also be a function pointer. So code in console driver would reduce to
if (grub_setkey_xlat)
grub_setkey_xlat(...)
Ah! Function pointers... I had completely forgotten about these.
It's been a while since I last did any coding in C, so my competence is
getting a bit rusty.
It clearly was high time to pick it up again...
