Hmm, so an idea I had just now.. can you grab a dump of the PCI config space for the disk controller in the MCFG vs non-MCFG cases? That is, find the device's address using pciconf -lv (e.g. pci0:0:30:0 or some such) and then run this command under both configurations and save the output: pciconf -r pci0:0:30:0 0:0xfc -- John Baldwin
