I had this problem once and I tried installing the package I could not 
remove (I reinstalled it) then I tried removing it.
That sometimes works, but what I would do in this case is to first disable 
the script by putting this on the first line after the line that has

#!/bin/sh

under that line add:

exit 0



that will disable the script so that perhaps kdm can start, then you can 
try to remove the gdm package.
