Maybe that code could be reused to generate an optimal geometry for
partitioning scheme like the amiga partition table, which support partition
granularity only on cylinder boundaries ? For the creation of new partition
tables this is, since the current scheme of using the <whatever> proposed
geometry often means the waste of disk space at the end of the disk.
