Thanks for your reply, but fttb it doesn't really help me.

I have tried with this Makefile:
    obj-m := gcdvd.o
    module-objs := gcdvd.o cache.o
But unfortunately cache.o isn't linked. After insmod gcdvd.o I get a unknown
symbol, tho it is defined in cache.o
A bit strange is that insmod gcdvd.ko doesn't work at all because of a bad
format or so. Only insmod gcdvd.o is accepted.

As alternative to above Makefile I can take:
TARGET  := gcdvd
WARN    := -W -Wall -Wstrict-prototypes -Wmissing-prototypes
INCLUDE := -I/usr/src/linux/include
CFLAGS  := -c -O2 -DMODULE -D__KERNEL__ -DKBUILD_MODNAME="${TARGET}" ${WARN}
${INCLUDE}
CC      := gcc-3.0

${TARGET}.o: ${TARGET}.c
cache.o: cache.S

.PHONY: clean

clean:
 rm -rf ${TARGET}.ko
 rm -rf ${TARGET}.o

But there is again the problem that I don't know how to extend it such that
it also links cache.o

Any help is appreciated!
