OK, is that a difference between board revisions, BIOS revisions or just
a misinterpretation of some superiotool dump?

I can see that your latest superiotool dump with the proprietary BIOS
has irq 0xc9 = 0x40 set. I tried to mirror that. Now the interesting
question is: Why does that setting not work for you?

To track this down, I need:
* superiotool dump of proprietary BIOS for board revisions 1.0, 1.1,
2.0, 2.x
* the exact BIOS version of the proprietary BIOS.

It seems that Ward's board also has 0xc9 = 0x40 set.
