The last BAR on the nForce4 ADMA controllers on this board are at 0xdfefe000 and 0xdfefd000. But it looks like PnP ACPI is also reserving those memory ranges:
Aug 30 14:08:02 alcor kernel: pnp: 00:09: iomem range 0xdfefd000-0xdfefd3ff has been reserved Aug 30 14:08:02 alcor kernel: pnp: 00:09: iomem range 0xdfefe000-0xdfefe3ff has been reserved
Which I very much doubt it should be doing, the BIOS doesn't need to reserve PCI BAR ranges in the ACPI tables. This sounds like a BIOS bug. You might want to check for an update from Supermicro.
