I edited the atkbdc_isa.c file as you instructed, rebuilt and installed my
kernel, but my integrated keyboard remains unresponsive with ACPI enabled.

No, the goal was to get atkbdc to try to attach to PNP0320 devices since those
have your keyboard I/O ports. Can you add some printfs to atkbdc_isa_probe()
to see how many times it is getting past the ID check, and how far along it
gets in each cases (i.e. which failure case causes the probe routine to return
an error)?

John,
I added some printfs to the isa_probe() function to see how far it was getting. The function is called many times as you can see in the dmesg, but mostly it exits at the PnP ID check with ENXIO.
At one point it gets further, but still exits with ENXIO when port0 is found to be NULL.
Any suggestions for further investigation?
