There is a trick to get umac.ko built for other kernels then default one.
Have a look at [1] and [2]. You need to have umac.ko from device and
remove some sections from it. Then cx3110x 1.x driver can be compiled for
it (I did not tried it with 2.0.15).

	cp ${WORKDIR}/umac.ko ${S}/src/binary_umac.o
	${OBJCOPY} ${S}/src/binary_umac.o -R __ksymtab
	${OBJCOPY} ${S}/src/binary_umac.o -R __ksymtab_strings
	${OBJCOPY} ${S}/src/binary_umac.o -R .gnu.linkonce.this_module
	${OBJCOPY} ${S}/src/binary_umac.o -R .modinfo
	${OBJCOPY} ${S}/src/binary_umac.o -R .init.text
	${OBJCOPY} ${S}/src/binary_umac.o -R .exit.text

Method with open source driver + firmware blob would be better but this
will rather do not happen as 770 and n8x0 are already on market so Nokia
wont spent any extra money on rewriting driver.
