Sort of works for me with 2nd gen iPod Shuffle. I was getting
different output from fdisk every time before the patch. After the
patch it's the same every time, but looks wrong:

$ fdisk sd0
fdisk: sysctl(machdep.bios.diskinfo): Device not configured
Disk: sd0 geometry: 242/64/32 [495616 Sectors] (2048 byte sectors)

Disklabel is also weird:

$ disklabel sd0
