I ran into the same problem a while ago.
This SiS5107 docking station bridge has header type 2 in his PCI config space header.
AFAIK this is bogus and not defined by the PCI standard.
Later 2.1.x kernels do not freeze, but do a
bad: printk(KERN_ERR "PCI: %02x:%02x [%04x/%04x/%06x] has unknown header type %02x, ignoring.\n", bus->number, dev->devfn, dev->vendor, dev->device, class, hdr_type);
in this case.
Maybe this code could be backported for 2.0.34?
