Acknowledge consent before login

[Stephen Berg (Contractor)]

I'm searching for a method to display a consent to monitoring statement 
on either GDM or KDM in Fedora 9.  I'm not tied into either display 
manager so whichever one is easiest to set up wins.  The message 
displayed is about 25 lines in a standard text file layout, and all 
users must acknowledge the statement by clicking an OK button before 
they are allowed a login attempt.  This was pretty easy to do under Core 
6 by having /etc/motd contain the required text and referencing it in 
/etc/gdm/custom.conf like so:

[greeter]
InfoMsgFile=/etc/motd
InfoMsgFont=Courier Bold 17
GraphicalTheme=Bluecurve

Has anyone found a way to set this up in Fedora 9?  GDM doesn't seem to 
pay any attention to the greeter section in custom.conf any longer.
