Yes, it fixes the problem, even without my modprobe.blacklist argument.

Some notes:

test-patches asked me for a flavour; I entered amd64.

When installing the linux-image package, I got this error:
update-initramfs: Generating /boot/initrd.img-4.5.0-0.bpo.1-amd64
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8107e-2.fw for
module r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8107e-1.fw for
module r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-2.fw for
module r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-1.fw for
module r8169
I ignored it, since I probably won't need WiFi during early start-up.
When fully booted with this kernel, I tested my WiFi and it still works.

lsmod shows now that the sp5100_tco module is loaded.

dmesg contains the following line:
[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.5.0-0.bpo.1-amd64
root=UUID=cab2c5d5-4664-4105-bcbd-fcb860cc035d ro quiet
(so it is version 4.5, without the blacklist argument)

dmesg does not show the ACPI error lines that were generated by the
faulty 4.5.

dmesg | grep sp5100_tco returns the following:
[   31.700531] sp5100_tco: SP5100/SB800 TCO WatchDog Timer Driver v0.05
[   31.700640] sp5100_tco: PCI Revision ID: 0x13
[   31.700709] sp5100_tco: failed to find MMIO address, giving up.

I hope this is what you expected. To me, it looks like the problem is
fixed.
