Unfortunately, it didn't make any difference.  After adding in the drive
IDs, they're identified correctly:

ata1(0): applying Seagate errata fix
ata2(0): applying Seagate errata fix

but I still get the corruption on md1 (sda1 + sdb1 in raid 1) but not on
either sda1 or sdb1 when the raid is shut down and the partitions are used
individually.

As a new test I made two raid1s, sda1+sda2 and sdb1+sdb2, and did the same
tests with both of them at once and there was no corruption.
