But still no lp0 showing in CUPS or Printer Admin (notice
I used the Linux term for it!)

After running the new_id command, do "lspci -k" again and see if it picked it up.
All the lcpci command pick it up.  They always do. There
is never an instance where they do not.

You're misunderstanding what I meant by "pick it up". I'm looking for a "Kernel driver in use:" or "Kernel modules:" line which doesn't seem to be showing up. "lspci" will always show the device because it exists regardless of whether or not there's a driver for it.

# lspci -k  -s 01:00.0
01:00.0 Parallel controller: MosChip Semiconductor Technology Ltd. MCS9900 Multi-I/O Controller
     Subsystem: Device a000:2000

Ran it anyway.  No joy.

Strange. I wonder why that isn't working. Given the similar supported ids, I expected that to work. Sorry, I have no more suggestions.

Btw, your original attempt at using the legacy ports is certainly not going to work. I saw this in one of your earlier emails:
    Region 0: I/O ports at e010 [disabled] [size=8]
    Region 1: I/O ports at e000 [disabled] [size=8]
Region 2: Memory at ac001000 (32-bit, non-prefetchable) [disabled] [size=4K] Region 5: Memory at ac000000 (32-bit, non-prefetchable) [disabled] [size=4K]
