Actually, it can be autodetected, but some of the X drivers are buggy. By 
overriding the autodetection, we won't find which drivers are buggy. Here's a 
message about it from the X list:

It sounds like the autodetection for your driver is broken. I think that 4 is 
the best general solution because users won't be surprised if they switch to 
xdm, gdm, or startx and all the fonts are suddenly way too big..

What we gain is that the Debian kde users will be excercising the X 
autodetection. And in the case where the autodetection works, it's obviously 
better to not throw that info away in kdm.
