There's a command-line flag to tell eeprom to ignorethe checksum:

	eeprom -i

However this snipit from the manual page may help even more:

     secure              none, command, or full.  If  secure=none
                         the  PROM monitor runs in the non-secure
                         mode.  In this  mode  all  PROM  monitor
                         commands  are  allowed  with no password
                         required.  If  secure=command  the  PROM
                         monitor  is  in the command secure mode.
                         In this mode, only the b (boot)  command
                         with  no parameters and the c (continue)
                         command  with  no  parameters   may   be
                         entered   without   a   password   being
                         required.  Any  other  command  requires
                         that   the   PROM  monitor  password  be
                         entered.  If secure=full the PROM  moni-
                         tor  is  in  the  fully secure mode.  In
                         this mode, only the c (continue) command
                         with   no   parameters  may  be  entered
                         without  a  password   being   required.
                         Entry of any other command requires that
                         the PROM monitor  password  be  entered.
                         Note: the system will not auto-reboot in
                         fully secure  mode.   The  PROM  monitor
                         password must be entered before the boot
                         process will take place.  When  changing
                         the  security  mode  from  non-secure to
                         either command secure or  fully  secure,
                         eeprom  prompts  for  the  entry and re-
                         entry of a new PROM password as  in  the
                         passwd(1)  command.   Changing  from one
                         secure mode to the other secure mode, or
                         to  the  non-secure mode does not prompt
                         for a password.  Changing to  non-secure
                         mode erases the password.

     password            PROM monitor  password  (8-bytes).   The
                         content  of  the password field is never
                         displayed to any user.  If the  security
                         mode  is  not  none,  the super-user may
                         change  the  PROM  monitor  password  by
                         entering:
                              example# eeprom password=
                         eeprom prompts for a new password to  be
                         entered and re-entered.
