So I'm trying to write a disklabel on a 240M disk so that I can write
the miniroot to the swap device and then install NetBSD 1.5.

Whe I attempt to write the disklabel to the disk I get warnings like
this for various partitions:

disklabel: WARNING: partition b: offset % cylinder-size != 0

And the disklabel doesn't get written...
