The begin of the partition has to be defined in cylinders:

        struct __attribute__ ((packed)) _SunRawPartition {
                u_int32_t       start_cylinder; /* where the part starts... */
                u_int32_t       num_sectors;    /* ...and it's length */
        };

IMHO it does not make sense to use non-cylinder alignment here.
