Mmm... For example, I get ~4M inodes per gigabyte on my machines with tmpfs.

It seems you're in fact using mdmfs(8) and that it is defaulting to creating some UFS filesystem instead of a tmpfs one. You can confirm that by running 'mount | grep -F /dev/md1' and checking the filesystem type (should be ufs, not tmpfs).

How is your md mounted? Could you provide the command-line, or the corresponding line in '/etc/fstab'? You should use 'tmpfs' as the device name in both cases.
