Well, if you're capable of building your own kernel, then you can get
the patch (which I've just refreshed and compile tested) from the
patches-that-need-love branch:

git checkout -b patches-that-need-love origin/patches-that-need-love
cp 0001-UBUNTU-SAUCE-no-up-ACPI-initramfs-DSDT-override.patch ..
git checkout -f master
git am ../0001-UBUNTU-SAUCE-no-up-ACPI-initramfs-DSDT-override.patch
fakeroot debian/rules updateconfigs
debuild -b
