So true.

Yes, I just did it for the heck of it:

piixide0       at pci? dev ? function ?

I assume one piixide in the whole system, because otherwise I'd
need to pin down at least the things above it.

comment out the pre-pinned wdc0 and wdc1:

#wdc0  at isa? port 0x1f0 irq 14 flags 0x00
#wdc1  at isa? port 0x170 irq 15 flags 0x00

un-wildcard the atabuses:

#atabus* at ata?

pin down the atabuses:

atabus0 at piixide0 channel 0
atabus1 at piixide0 channel 1

un-wildcard the drives:

#wd*   at atabus? drive ? flags 0x0000

and pin down the drives in an insane order to test this:

wd0    at atabus1 drive 1 flags 0x0000
wd1    at atabus1 drive 0 flags 0x0000
wd2    at atabus0 drive 1 flags 0x0000
wd3    at atabus0 drive 0 flags 0x0000

I tested this, makes the first drive on the first channel wd3.

But, yes, like Thor said, it's most often simpler (at least if your not
doing this constantly) to just edit fstab.  (Or just ignore fstab and mount
manually.)

On my Abit board with a viaide and a hptide, I usually go the fstab route
when I rearrange drives.

That being said, I don't think autoconf(9) is quite flexible enough to
do enumeration like Linux does.  But then again, it is flexible enough
to allow manual enumeration.  Whatever.
