removing a debian package

[Nick Gawronski]

Hi, I used the make-kpkg script to build a kernel but the kernel would not 
properly boot so I want to remove the package.  I tried typing dpkg -r 
kernel-image, kernel, kernel-image-2.6.17.7 and dpkg says package is not 
installed for every name I tried.  How can I remove these packages or get 
the name that dpkg says a package is called?  I looked in /var/lib/dpkg but 
nothing in that directory could help me.
