Oh, yes! This is the old weird thing! SuSE uses to install kernel sources
in /usr/src, and I blindly followed :( fixed now :).
So, finally, we have a nice Makefile suitable for 2.4 and 2.6 (>= 2.6.6) kernels:

# Template Makefile for external module compilation
#
# replace <mod-name> with the prefix of the target module
# replace <mod-object-list> with the list of object files to be linked together
# replace <mod-export-list> with all symbol-exporting object filenames
# additionally specify EXTRA_CFLAGS, if needed

KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
KERNEL_24 := $(if $(wildcard $(KDIR)/Rules.make),1,0)

Regards, thanks for your helpful advice and
have a nice weekend,
