I received the right hint from Gerardo Poggio, so I post it here 
for future reference.

The solution (to make the DPKG_ARCH=armel and KERNEL_ARCH=arm) 
was to edit 
/usr/share/kernel-package/ruleset/misc/kernel_arch.mk, and add 
the following lines at the end:

ifeq ($(strip $(architecture)),armel)
  KERNEL_ARCH := arm
endif
ifeq ($(strip $(architecture)),armeb)
  KERNEL_ARCH := arm
endif

Then I run:

cd /usr/src/linux
export CROSS_COMPILE=arm-linux-gnueabi-
export ARCH=arm
make-kpkg --arch armel --cross_compile=arm-linux-gnueabi- clean
make-kpkg --revision=lacie.0.1 --initrd --arch=armel \
          --cross_compile=arm-linux-gnueabi- kernel_image
make uImage
