I got a tip from Navin at https://bugzilla.kernel.org/show_bug.cgi?id=118401
to try acpi=noirq and this does not only let me boot kernels>=4.3 (I'm writing this from mainline 4.7!), but also makes it poweroff and restart correctly.
However, it does not resume from suspend (it seems to suspend as it should, but clicking the power button to turn it back on does nothing).
