OFPW (the latest version) is a universal binary and works. OFPW -command 0
will turn it off.
You could also use NVRAM, built in to the OS....
Sudo nvram -p shows you all the variables currently in your nvram....
sudo nvram security-mode=none
Turns off security, to turn it on
sudo nvram security-mode=command
To set the password, you need to know the encrypted version of it....set the
password on another machine, then use sudo nvram-p to see it, copy the
encrypted form of the password and use
sudo nvram security-password=<place encrypted password here>
sudo nvram security-mode=command
I use this from LANrev and sending unix scripts to set users firmware
passwords that may be wrong....or missed during a service call.
You can script a firmware password check script using openssl so that you
don't have to put the weakly encrypted password in a visable script...

I started documenting things I do like this in my blog...if you can call it
a blog 8-)...
