I use the following 2.6 Makefile template for an out of kernel drive I 
am forced to use:
----
alex@...k:~$ cat /usr/src/wag54g/sangam-atm/Makefile 
ifneq ($(KERNELRELEASE),)
include Kbuild
else
        KERNELDIR      := /usr/src/wag54g/linux/
all::
        $(MAKE) -C $(KERNELDIR) M=`pwd` tiatm.ko
endif
alex@...k:~$ cat /usr/src/wag54g/sangam-atm/Kbuild 
obj-m                   := tiatm.o
tiatm-y                 := cpsar.o aal5sar.o tn7sar.o tn7atm.o tn7dsl.o dsl_hal_api.o dsl_hal_support.o dsl_hal_advcfg.o

ccflags-y               += -I$(PWD) -DPOST_SILICON -DCOMMON_NSP -D__NO__VOICE_PATCH__ -DEL -DCPATM_TASKLET_MODE
#ccflags-$(DEBUG)       += -D....
---- 

It's not great, but it works.

Cheers
