So far the MBR slice for netbsd was always d: not c: on i386 ata 
(wd?) disks. This is the way the default 1.6.1 install constructed it 
and I left it alone.

quoting disklabel manual:
"
BUGS

    If the disk partition is not specified in the disk name (i.e. 
``xy0'' in-stead of ``/dev/rxy0c''), disklabel will construct the full 
pathname of the disk and use the ``a'' partition on the tahoe, the ``d'' 
partition on i386 or hpcmips or arc, and the ``c'' partition on all 
others.
