You're right by all means. AGP bridges are _always_ positive decoders.
The problems you've seen were caused by the wrong semicolon somehow
sneaked into the patch:

+static void __init pci_fixup_transparent_bridge(struct pci_dev *dev)
+ if ((dev->class >> 8) == PCI_CLASS_BRIDGE_PCI &&
+ (dev->device & 0xff00) == 0x2400);
^ Ugh..
+ dev->class |= 1;

Which means that I'm setting bit 0 in the ProgIf for _all_ Intel devices...
I'm really sorry about that.
Thanks for the pci dump - it's very useful anyway.
