Also, the mem resources of the SATA controller are used for AHCI
(however, PATA compatibility mode is supported using the port ranges,
which is what the controller is forced to do). In addition, the device
name string on the SATA controller is only there because I've been
fooling with ata-chipset.c (to unsuccessfully attempt to get AHCI
working). Reading the MMIO registers in AHCI mode seems to produce
spurious instances of reading garbage data, followed by reading the data
that I want.

For instance, in ata-chipset.c line 771 ata_ahci_reset():
    if (!(ATA_INL(ctlr->r_res2, ATA_AHCI_PI) & (1 << ch->unit))) {
        device_printf(dev, "port not implemented\n");
        return;
    }

Produces "port not implemented" whenever it is executed (it ends up
reading 0x00020070 or a similar unexpected value. However, if I put
another ATA_INL(ctlr->r_res2, ATA_AHCI_PI) just above the if()
statement, it will read 0x00000001, which is the expected value for my
situation (a single port SATA controller on a laptop). This is supposed
to read a bitmap of the enabled ports on the SATA controller.

Attaching dmesg:

You'll notice the "fpudna in kernel mode!" and "ndis0: bssid_list
failed" messages. These are related to an NDIS 5.1 wifi driver and don't
apply to my problem.
