Drives defined with -drive if=ide get get created along with the IDE controller, inside machine->init(). That's before cmos_init(). Drives defined with -device get created during generic device init. That's after cmos_init(). Because of that, CMOS has no information on them (type, geometry, translation). Older versions of Windows such as XP reportedly choke on that. Split off the part of CMOS initialization that needs to know about -device devices, and turn it into a reset handler, so it runs after device creation.
