In theory, the Cygwin DLL has to provide stuff through ioctl's after
opening the device file.  There are already quite a few ioctl's
supported, namely

HDIO_GETGEO, BLKGETSIZE, BLKGETSIZE64, BLKRRPART, BLKSSZGET, BLKIOMIN,
BLKIOOPT, BLKPBSZGET, BLKALIGNOFF, RDIOCDOP subcommand RDSETBLK,
RDIOCGET.

Whatever is missing *and* is provided by the WinAPI function
DeviceIoControl (or, actually, any other way) can be added to
Cygwin's ioctl API as you see fit.
