did a quick test, packages and module compile without problems,
importing, scrubbing and some regular create/destroy/.. operations also
work as expected. will do some more in-depth testing tomorrow and report
back.

@Achim: you should be able to do the following (after installing git,
git-buildpackage, the build-dependencies of zfsutils-linux and maybe
some other stuff ;)):

$ git clone git://anonscm.debian.org/pkg-zfsonlinux/zfs.git
$ cd zfs
$ git checkout -b testdebiankernelfix
Switched to a new branch 'testdebiankernelfix'
$ gbp dch --debian-branch=testdebiankernelfix
$ sed 's/zfs-linux (0.6.5.8-2)/zfs-linux (0.6.5.8-2~test1)/' -i
debian/changelog
$ git commit -am "update changelog"
$ gbp buildpackage --git-no-pristine-tar
--git-debian-branch=testdebiankernelfix -uc -us

now you should have the following files:

$ ls -1 ../*0.6.5.8-2~test*.deb
../libnvpair1linux_0.6.5.8-2~test1_amd64.deb
../libuutil1linux_0.6.5.8-2~test1_amd64.deb
../libzfs2linux_0.6.5.8-2~test1_amd64.deb
../libzfslinux-dev_0.6.5.8-2~test1_amd64.deb
../libzpool2linux_0.6.5.8-2~test1_amd64.deb
../zfs-dbg_0.6.5.8-2~test1_amd64.deb
../zfs-dkms_0.6.5.8-2~test1_all.deb
../zfs-dracut_0.6.5.8-2~test1_all.deb
../zfs-initramfs_0.6.5.8-2~test1_all.deb
../zfsutils-linux_0.6.5.8-2~test1_amd64.deb
../zfs-zed_0.6.5.8-2~test1_amd64.deb

install the subset of those which you currently have installed (probably
not the dracut, -dbg and -dev ones, maybe not the zfs-zed one, most
likely everything else ;)) with "dpkg -i" and it should trigger a
rebuild of the zfs module during installation.

I replaced the version number such that it is higher than the one
currently in stretch/sid (to make it obvious which one you are using),
but lower than the next regular update by the maintainers (so that that
will not be skipped).
