Works somewhat:

  PCIrootbridge => new Pci_iomem_root_bridge()
  {
    .hid       = "PNP0A03";
    .iobase    = 0x62000000;
    .iosize    = 0x00010000;
    .dev_start = 0x64000000;
    .dev_end   = 0x6fffffff;
    .int_a     = 80;
    .int_b     = 81;
    .int_c     = 82;
    .int_d     = 83;
  }

But there are still little things... we're looking into it.
