Just have tested by doing several reboots with boot option 2 ("with ACPI 
disabled") and different combinations of ACPI-related BIOS options. 
Unfortunately, this doesn't seem to have any effect. Module miibus still 
tells that "PHY not found". All registers it is trying in mii_phy_probe are 
0. Not right bus or registers tried?

BTW, that brand of Intel PCI hub (ID 0x2580) is mentioned specifically in 
freebsd-current sources, in /sys/i386/pci/pci_cfgreg.c:150:

        /*
         * Grope around in the PCI config space to see if this is a
         * chipset that is capable of doing memory-mapped config cycles.
         * This also implies that it can do PCIe extended config cycles.
         */

        /* Check for the Intel 7520 and 925 chipsets */
        vid = pci_cfgregread(0, 0, 0, 0x0, 2);
        did = pci_cfgregread(0, 0, 0, 0x2, 2);
        if ((vid == 0x8086) && (did == 0x3590)) {
                pciebar = pci_cfgregread(0, 0, 0, 0xce, 2) << 16;
                pciereg_cfgopen();
        } else if ((vid == 0x8086) && (did == 0x2580)) {
                pciebar = pci_cfgregread(0, 0, 0, 0x48, 4);
                pciereg_cfgopen();
        }

But whether it is of any significance is beyond my understanding... :)
