That's a good question. I guess there may be others in the same family with the same bug. I don't really know.
The replacement, AT49BV642D, does not have this bug.

That's interesting...especially since u-boot only reads the low byte of the JEDEC ID, so adding a fixup for one particular ID may match tons of chips with 16-bit IDs.
I'll have to check the latest u-boot and see if it breaks any of my boards.
