Ok, I have something for a quick try. Can you add the following code to
auto.c and try enabling serial once with 2e and once with 4e afterwards?

You might have to adapt the PCI ID of the south bridge's LPC interface
device (24cc in the below example)

The code won't patch, but it should serve as a template

Just so we see whether this makes it work.
