Cant get Blender work with CUDA 6.5

Hi guys. I'm trying to use CUDA in blender. I have a CUDA 7.0 unsupported Nvidia card (GTS 250) so i had to install CUDA65 from the AUR. I have these packages in:

local/cuda65 6.5.19-1
    NVIDIA's GPU programming toolkit (for compute capability <
    2.0)
local/lib32-nvidia-340xx-libgl 340.96-1
    NVIDIA drivers libraries symlinks (32-bit)
local/lib32-nvidia-340xx-utils 340.96-1
    NVIDIA drivers utilities (32-bit)
local/lib32-opencl-nvidia-340xx 340.96-1
    OpenCL implemention for NVIDIA (32-bit)
local/libvdpau 1.1.1-2
    Nvidia VDPAU library
local/nvidia-340xx-dkms 340.96-13
    NVIDIA driver sources for linux, 340xx legacy branch
local/nvidia-340xx-libgl 340.96-1
    NVIDIA drivers libraries symlinks
local/nvidia-340xx-utils 340.96-1
    NVIDIA drivers utilities
local/opencl-nvidia-340xx 340.96-1
    OpenCL implemention for NVIDIA

Besides Blender 2.77. At first I used CUDA 7, but uninstalled it.

Now, i try to run Blender as normal user as well as root, and can't choose CUDA in the System>Compute Device option, just CPU. In the CLI I see no errors.

I dont know what i'm missing here, any tip? Thanks!

2 things come to mind :

you are using dkms versions of the nvidia kernelmodules, do things work if you use the stock (or lts) kernel with the precompiled binaries from nvidia-340xx ?

Cuda 7.5 / 8 don't support gcc 6 and depends on gcc 5. one would expect cuda65 to also need gcc5 or even gcc 4.9 .

hmm, cuda65 last update was on 2015-11-28 15:51 .
AL was on gcc-5.2.0-2 then, seems worth a try to adjust the cuda65 pacakge to use gcc5 ,similar to what the stock cuda package does.
