also having the same problem:

installed feisty from desktop cd, normal options. did not do any apt-get upgrades. apt-got openssh-server, vim-full and samba, plus sysv-rc-conf, then:

1. apt-get install ncurses-dev kernel-package linux-source build-essential gawk linux-kernel-devel
2. cd /usr/src
3. tar jzxvf linux-source-2.6.20.tar.bz2
4. ln -sf linux-source-2.6.20 linux
5. cd linux
6. uname -r ==> 2.6.20-15-generic
7. cp /boot/config-`uname -r` ./.config
8. make-kpkg --initrd --append-to-version=-custom01 kernel_image kernel_headers
9. du -sh ../linux-image*.deb
226M ../linux-image-2.6.20.3-ubuntu1-custom01_2.6.20.3-ubuntu1-custom01-10.00.Custom_i386.deb
