That explains why

ROM:00000000 1001 move.b d1,d0
ROM:00000002 8000 or.b d0,d0
ROM:00000004 0000 0008 ori.b #8,d0

doesn't make sense...
However, see how the OF does it:

seg018:30EB8C3A reboot: ; DATA
XREF: p_PMU_handle_event+72
seg018:30EB8C3A 2E7C 3100+ movea.l #$31000000,sp
seg018:30EB8C40 207C 0000+ movea.l #8,a0
seg018:30EB8C46 4ED0 jmp (a0)

I wonder what is stored at 0x4, though.
