Kevin,
here is a fixup for the geometry detection. We tried to be overly
clever and calculate the cyclinder size for devices > 64k cyls. Now
this is wrong for the cyls parameter as the interface only has
16bit. Large DASD devices have a special token (0xfffe) that
indicate to the DASD related code, that you have to calculate
the cyls size yourself.
Without this patch QEMU cannot pass through bigger DASD disks
and complains "cyls must be between 1 and 65535"
