Thanks for pointing me to the Mainline Builds. When I tried to install
"linux-headers-3.18.0-031800rc1-generic_3.18.0-031800rc1.201410192135_i386.deb"
et.al. I ran into the problem described in #1358966.
I'm not sure if the proposed patch would help to solve my problem -
after further debugging it seems that the pure hardware itself seems to
be recognized, but a wireless network connection cannot be established:

After rebooting into the new kernel the trackpad did not work and due to
the missing module no WLAN was available.
