IIRC the recommended way to get cx3110x support is to use cx3110x-devel
mailing list: https://garage.maemo.org/mailman/listinfo/cx3110x-devel

BTW, there is a set of community enhancements and patches for cx3110x
driver (Nokia 770 version) collected together by Rodrigo Vivi and posted
here: https://garage.maemo.org/pipermail/cx3110x-devel/2008-April/000038.html
