If you have write access to /etc/kderc, it's possible to lift the restrictions 
for a specific user. Unfortunately this change is unlikely to get picked up 
by already running applications.

If all you want is a shell, it's easier to just prompt for a password and 
start a shell from a shell script. Something like:

$crypted_pw=$(kdialog --password pw | 
			perl -e  'while (<>) { print crypt($_, "xx")."\n"; }')

if [ $crypted_pw == $yourCryptedPw ]; then
	/opt/kde3/bin/konsole
fi

You can use khotkeys to bind the script to a hotkey.

Cheers,
Waldo
