Well, okay, there's two ways you can build a single module in a directory in 2.4, one is to have
O_TARGET := module.o obj-m := $(O_TARGET)
obj-y := part1.o part2.o
The other is
O_TARGET := something.o obj-m := module.o
module-objs := part1.o part2.o
(plus a link rule for module.o)
In 2.5, only the second way is legal, so if you're aiming for a compatible Makefile, you'd use that one, and then O_TARGET shouldn't matter for "make modules".
