Its pretty obvious Jacques that you have never worked with Nokias to make a
statement like that. 

Password Recovery on an IP series is trivial once one has access to the
console. 

Abridged from resolution 692 on http://support.nokia.com/

Interrupt the boot process and boot it single user by issuing "boot -s" at
the BOOTMGR> Prompt. 

run /etc/overpw to blank out the old password. 

reboot the box et voila. IIRC 3.4 is marginally more involved as it doesn't
like blank passwords. But that trivial compared to ripping the hard disk
out. 

Note to Mike : Get yourself access to the Nokia KB PDQ, its very
comprehensive & will aid you in your quest. 
Whilsts you are in single user mode on the module 'rm /active/config' also
to get rid of any existing config.

Wrong!

You haven't worked with FW-1 either given that its trivial to add a new
superuser to the module using "fwm -a" from the shell as documented here
