So I might have trouble bisecting, as stone-age kernels don't seem to
boot on my installed system cleanly any more; some kind of
incompatibility with my encrypted partitions. But I booted an F16 live
image, which has kernel 3.1.0, and that reboots quickly. If I'm reading
things correctly, mjg59's patch went into kernel 2.6.39, so if that was
causing the problem, I'd expect the F16 live image to have a slow
reboot.

I'll go back through the live images for F17->F19 and see when the
reboot gets slow, which will give us a very rough range to look at, at
least. I'll also try Rafael's suggestion re acpi_osi.
