I think you should have done something other than kernel-image. Kernel-image
does not build modules, I think. Look at man page carefully.

Also, even when upgrading across major versions, it is a good idea to cross
check your .config against the known, working .config, in your case the
.config of 2.4.25 kernel.

Luckily you can easily boot back into 2.4.25, because you did the install
the Debian way, I hope.
