It would be better to start with the configuration of Debian's -amd64
images if you want to use a 64-bit kernel, or even install and boot the
2.6.26-2-amd64 kernel.

That's because there are numerous changes between 2.6.26 and 2.6.32, so
your old configuration cannot be used as-is.
You may want to run "make ARCH=x86_64 menuconfig" first, so that the
defaults are used. Otherwise you will have to answer literally
thousands of questions.
