I didn't compiled the driver myself, got it from a repository. I'm afraid that applying a patch and compile the driver is out of my knowledge... But I'm more than happy to follow instructions.

If you can download the source to your kernel, copy the patch to the root of the kernel tree then do the following:

patch -p1 -i dpm_vblank_dump.diff make -j5 sudo make modules_install sudo make install

Then reboot and select the new kernel from the grub menu.
