generic bridge support was biting us more than it helped, whenever a new chipset came out from a vendor and misprogramming it caused strange hangs or corruption. [2] Add a large number of PCI IDs based on what the linux drivers support. Note that the new PCI IDs haven't been tested, they're just *likely* to work. In particular the VIA AGP 8x chipsets are concerning, due to lack of testing, possible issues (kern/69953), and not having a nice "does this bridge say it would do 8x" function. However, this shouldn't make the situation worse, since these chips would have probed in the past anyway.
