A followup on this. First of all, I didn't realize that the PCI
configuration
space is dynamic - things change all the time.

Secondly;

As it turns out, those three bytes change constantly, so I guess they
are not
significant.

Also, I missed one byte that IS consistently different after a boot with
the
proprietary BIOS:

0000:01:04.3 Bridge: Advanced Micro Devices [AMD] AMD-8111 ACPI (rev 05)
...
-40: 80 f1 00 04 00 00 00 00 20 14 50 00 00 00 00 00
+40: 80 f1 00 07 00 00 00 00 20 14 50 00 00 00 00 00

How would I go about changing that byte during the LinuxBIOS boot? Do I
need
to edit resourcemap.c in src/mainboard/tyan/s2881?

Thanks,
Ward.
