It looks like the generic ide code now wants ide_init_hwif_ports() to set
the parent struct device into the ide_hw structure (new field ?).  Without
this, the mac ide code can cause the ide probing code to explode in flames
in sysfs registration due to what looks like a stale pointer in there
(happens when removing/re-inserting one of the hotswap media bays on some
laptops).
