This solution worked like a charm! Thanks Arjan!
One note: use "set ..." syntax in the interactive loader prompt (6), and use
"hw.ata.ata_dma="0" *without* "set " in /boot/loader.conf
Interestingly, setting the drive in the BIOS to PIO4 mode had no effect.
Now if I can just get carrier on my vr0 interface, I won't have to return this system!

Yes, I had the same problem.
If this is a 2.5" drive, it probably doesn't have a 80-pins cable. Force PIO mode for the install by entering at the boot prompt (option 6 in the boot loader menu): set hw.ata.ata_dma="0" boot
After you've installed the system, insert that line into /boot/loader.conf, and load up "atacontrol mode 0 udma33 udma33" as early as possible during the boot (try using /etc/rc.early, for example) to get it up to speed again.
