Doods, you seriously need to join a sarcasm workshop.

The low-level detection is necessary because this issue not only applies to KDM. Say you are logged in and KMail explodes because you again ran out of disk space.
KDE/Qt should have a nifty system to early detect diskspace shortage and warn the user, so he can do something about it _before_ problems appear.
