Xfree86 video buffering?

Recently I have noticed that after shutting down my machine or rebooting
my X-windows will briefly flash an image of whatever I was doing when I
rebooted the machine or logged out.
As an example if I was browsing porn at night in mozilla just before I
clicked "K->Logout...->Reboot Computer" in KDE, the next morning when my
Girlfriend turns my computer on she gets a quick 2 second shot of my
porn just before the KDM login screen.
What causes this? Can it be prevented? I can certainly see sensitive
data potentially being leaked via this quirk.
