Is this a P-4 Xeon with a PCI-X bus?  If so, I'm guessing that this
IBM chipset is really a re-badged serverworks chipset, given the
serverworks southbridge (pci0:15).

You might want to try a patch to sys/i386/isa/pcibus.c similar to the
one in kern/38894, using 0x010f1014 in addition to 0x02011166: and
0x03021014 in addition to 0x00111166.  Eg:

	 case 0x00061166:
               /* FALLTHROUGH */
	 case 0x00081166:
               /* FALLTHROUGH */
         case 0x00101166:
               /* FALLTHROUGH */
         case 0x010f1014:
               /* FALLTHROUGH */
         case 0x02011166:
               /* FALLTHROUGH */
                s = "ServerWorks host to PCI bridge";
                *busnum = pci_cfgread(cfg, 0x44, 1);
                break;

<...>

        case 0x00111166:
               /* FALLTHROUGH */
        case 0x03021014:
                s = "ServerWorks CMIC-HE";
                *busnum = pci_cfgread(cfg, 0x44, 1);
                break;
