AFAIR bootsched is supposed to be used on Oldworld Macs only. It works by
addressing the PMU that hangs off the ADB interface chip on these old
Macs. Newworld Macs need another way of writing to the PMU, only nobody
figured it out yet. I tried, based on the OF code for scheduled bootup,
but could not make this work in Linux.
IOW, this is not a bug but misuse of bootsched. I will update the man page
to make this clear.
