I see no such warning in the log you attached, so it's not the issue, as it seems.
Below is a debug patch, and now you should see messages like "XXX ..." in kernel log at loading the driver. If there is no such a message, it means that the thinkpad hook isn't built in at all. Please check the kernel log again with the patch.
Actually, before adding your debug patch, a question about something that may be relevant here: I noticed just now that the kernel build, which I performed in accordance with the instructions from the Archlinux Wiki:
https://wiki.archlinux.org/index.php/Kernels/Compilation/Traditionaldid not result in a /lib/modules/extramodules-3.19-ARCH-gdg01 directory being created ("ARCH-gdg01" being the suffix used for the custom-built kernel).
The only extant modules directories are /lib/modules/3.19.3-ARCH-gdg01 and of course the extramodules dir /lib/modules/extramodules-3.19-ARCH that already existed from the previously installed ARCH distro kernel.
I suspect this may be a problem vis a vis ACPI, because with the new kernel loaded, the battery level indicator is stuck at zero. :)
What's the magic incantation to build the extramodules? I did look through this:
https://www.kernel.org/doc/Documentation/kbuild/modules.txtbut it did not seem to address this question that I could tell.
I have no idea about Arch, but in general, an easy way to build a module externally is to copy the kernel source tree (or a part of it), build it with M=xxx make arguments and install with INSTALL_MOD_DIR override.
% mkdir -p /somewhere/kernel/sound/pci % cp -a /usr/src/linux-xxx/sound/pci/hda /somewhere/kernel/sound/pci/ % cd /somewhere/kernel/linux-xxx % patch -p1 < /somewhere/somefix.patch % cd sound/pci/hda % make -C /lib/modules/$(uname -r)/build M=$(pwd) % su # export INSTALL_MOD_DIR=updates # make -C /lib/modules/$(uname -r)/build M=$(pwd) modules_install
But better to consult anyone familiar with Arch.
