There's your problem; you're still running the installer kernel.  The 
installer kernel is only supposed to work well enough and for long enough for 
you to build yourself a new one.  Install kernel-package, libncurses5-dev  
(menuconfig needs it);  then you can just get sources from kernel.org, and 
compile them into a .deb package to install with dpkg -i.

Note: unless you're *very* lucky, you *will* at some point turn off something 
you should have left on and your new kernel won't boot.  Save all your config 
files, have a bootable CD handy, and learn how to use it to alter your LILO 
or GRUB configuration to boot the installer kernel.  

If you're still running a "stock" kernel, you're only using about half the 
power of Linux .....
