You said you had this in your kernel config:

# ATA and ATAPI devices
device          ata0    at isa? port IO_WD1 irq 14
#device         ata1    at isa? port IO_WD2 irq 15

The device you commented out was ata1 at isa.

Here is your dmesg:

atapci0: <Intel PIIX4 ATA33 controller> port 0xf000-0xf00f at device 7.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0

The device probed was on pci0.

As far as I can see, when the ata driver attaches via pci, there is no
way to disable ata1 from the kernel config file.

I don't know the answer to this either.  But did you try Igor Bykhalo's
suggestion of putting 'di ata1' in your /boot/loader.conf?
