This works for me. Thanks for the feedback!
For any others wanting to walk this path in the near future, here's the
entire sequence that is working for me (as of kernel and tools pulled on
2016-05-13):
bcache format --tier 0 --bucket=512k --cache_mode=writeback \
-C /dev/nvme0n1 \
--tier 1 -C /dev/sdd1
echo /dev/sdd1 > /sys/fs/bcache/register
echo /dev/nvme0n1 > /sys/fs/bcache/register
mount -t bcache /dev/nvme0n1:/dev/sdd1 /mnt/whatever
Regards,
-Martin
