The memory allocated for the SATA controller in the same southbridge has already taken a chunk of that space for itself. This might also explain some weirdness when the AHCI system is attempting to interact with the MMIO space... Andy, can you check your dmesg and verify this is also true on your machine? I looked at what you sent to me and it looks like this is the case (though your mem ranges are in 0xd04xxxxx). What to do about this? -- Coleman Kane
