This tweak here forces openssh to use PAM auth for cleartext passwords, and this tweak here causes PAM to allow null passwords through the pam_unix.so auth module.
Unfortunately, out of the box, the Angstrom root user does not have a null password, he has NO password, a subtle difference and the user gets a password authentication issue when trying to log in through ssh with a null password.
This stackexchange question here provides an answer to the problem. (See the update at the bottom of the first answer).
/etc/shadow needs to have the encrypted value for null password saved for the root user. For example:
root:U6aMy0wojraho:13721:0:99999:7:::
When I add this to my /etc/shadow file, I can log in with no problem now through ssh.
