Many 64-bit PCI-X cards are designed to work in 32-bit mode if inserted in shorter 32-bit connectors, with some loss of speed. An example of this is the Adaptec 29160 64-bit SCSI interface card. However, some 64-bit PCI-X cards do not work in standard 32-bit PCI slots.
Installing a 64-bit PCI-X card in a 32-bit slot will leave the 64-bit portion of the card edge connector not connected and overhanging. This requires that there be no motherboard components positioned so as to mechanically obstruct the overhanging portion of the card edge connector.

1064MB/s (PCI-X 64-bit bus @ 133MHz) |
des weiteren sehe ich den begriff "pci-x" in dem von "lspci" ausgegebenen text, ist alles alles "pci-x", die abwärtskompatibilität kommt somit nicht zum einsatz...Da wäre ich mir nicht so sicher, denn die Slots sind definitiv nicht PCI-X.
