Hello, 

Yes it should work. 331.20 and 331.38 kernel modules should compile without 
patching on kernel version 3.12.xx - but not 3.13. UVM module maybe not, as 
reported by different users here and on the NVIDIA developer forums, thus 
requiring --no-unified-memory switch on the nvidia-installer. 

331.38 requires the patch mentioned to compile the kernel module, because of 
some kernel changes to acpi event flags waiting introduced with kernel 3.13. 
Also the patch fixes another change needed for loading the UVM module, which 
although compiles OK, errors out when trying to load it (modprobe) with the 
some EUID error. The patch fixes that. This was for 3.13-rc, while NVIDIA 
doesn't officially support devel-version kernels. 

331.38 works quite OK and doesn't screw things like 331.20 did. I'm using it 
like I said for a while now (actually right after release) and with every 
3.13-rcX update in K:HEAD repo that I got, ran the 331.38 patched driver 
installer, rebuilt the kernel and it worked without problems.)

Regarding the usage of K:HEAD and 3.13.rc kernel versions, I was curious about 
the multi-queue block layer, but I'm already planning a reinstall of 13.1 
using btrfs so I'll be using whatever is in the update channels or like you 
suggested in K:stable.

Short procedure for installing 331.38 is:

Get the 331.38.run install file. 

0. Boot with kernel param 3 or in terminal as root do systemctl stop xdm.
1. sh NVIDIA...331.38.run -x to extract. 
2. cp nvidia_3.13_kernel.patch to NVIDIA...331.38 folder
3. Apply patch with patch -p 1 -i ./nvidia_3.13_kernel.patch for example.
4. ./nvidia-installer -a
5. Reboot.
6. Profit.
