Two things:
- you need to set the fstype as '4.2BSD', and set the cpg field to '16'
  (the latter can be overridden by the -c option to newfs)

- The '*' after the cylinder start/end values in the comment is
  because your partitions aren't on cylinder boundaries. I suggest
  that you make your partition sizes multiples of '798' (sec/cyl).
  My usual method of doing this is:
	round(part_size_in_MB * 2048 / sec_per_cyl) * sec_cyl
  So, sd0a would be either 130872 long
  The reason for doing this is for a) performance, and b) some systems
  don't like swapping onto swap partitions that aren't on cylinder
  boundaries.
