I think KDE calls the kdesktop_lock helper tools when it wants to lock the 
session, so you could rename this utility and create a script with the 
original name that does your additional commands and the calls the renamed 
tool.

Not sure about the unlocking, my guess is that kdesktop_lock blocks (does not 
return) until the unlock, so the script might be able to handle the 
additional unlocking operations afterwards as well.

Cheers,
Kevin
