v3 of the patch is available, which includes hashing functions
and documents the expected input format when using those functions.
I don't have the updated module on any of my servers yet, but
running slappasswd from my build directory does seem to yield
the same results as the non-password versions:

$ ../../../../servers/slapd/slappasswd -T passwd -o module-load=`pwd`/.libs/pw-totp.so -h "{TOTP1}"
New password: 
Re-enter new password: 
{TOTP1}GAYA====

$ ../../../../servers/slapd/slappasswd -T passwd -o module-load=`pwd`/.libs/pw-totp.so -h "{TOTP1ANDPW}"
New password: 
Re-enter new password: 
{TOTP1ANDPW}GAYA====|{SSHA}Qo6WiIWWsWohlwZSo9oQkImKvSNArGio

This is using an OTP seed of 00 and a password of foo
