I got a new mobo because the old one got fried somehow^^
I could provide GPIO values from inteltool with both daughter boards. So someone could write better handling code. But how do I do that specifically?

It would be nice if we push that change to the mainline, but I believe that it was declared as 0x87 on a purpose.
I assume bit 2 simply turns the FW function on and off. People without a FW connector would simply see a spurious FW controller. But we can do better of course :)
Probably because of the USB/modem version of the chip? We will have to detect this somehow, so other people won't have to be in the same situation. Any ideas? I will try to spend some time during the weekend.
There is a 1394_DTCT line in the schematics. It goes straight to GPIO16 of the PCH. It has a pull-up on the mainboard, so if GPIO16 is low, we should have FW => 0x83 if it's high => 0x87.
If you can switch between the daughter cards easily, please check GPIO values with inteltool (in util/inteltool/ of the coreboot tree) for each card.
