It is no problem to use the same Makefile for both 2.4.x and 2.5.x,
and even let the Makefile do the RightThing[tm] in case the user just
types 'make'.  My Makefiles for kernel stuff look like this (stripped
down a bit):

==============================[ cut here ]==============================

ifneq ($(KERNELRELEASE),)
# call from kernel build system

obj-m	:= btaudio.o

-include $(TOPDIR)/Rules.make

else

KDIR	:= /lib/modules/$(shell uname -r)/build
PWD	:= $(shell pwd)

default:
	$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

endif

==============================[ cut here ]==============================

If you need different stuff for 2.4.x and 2.5.x you can handle it
using ifeq ($(VERSION).$(PATCHLEVEL),2.4)
