 * A few comments:
 * 
 * 	* This empirically isn't hard to do (not that you'd suspect it
 * 	  would be).  We have a NetBSD/i386 installation procedure at
 * 	  MIT (highly tailored to our environment), and it uses
 * 	  megabyte measurements.  We don't even bother to round up to
 * 	  the next cylinder boundary (is there really an advantage any
 * 	  more?), but that would be an easy addition.

The advantage is that you don't get messages like "Cannot allocate full
cylinder in last cylinder group" or some such when you newfs a partition.

I should post my disk partition calculator one of these days -- it will
figure out cyl -> (raw, FFS) MB, FFS MB -> cyl and raw -> cyl mappings.
The FFS mappings are accurate to less than 1%.
