This sounds pretty tedious unless such transformations can be automated.

I posted what I observed about it before here:

  http://mail-index.netbsd.org/port-evbmips/2012/06/08/msg000141.html

The culprit appears to be "netbsd32___mount50()".

I'll see about getting a current picture soon.

For historical background see:

  http://mail-index.netbsd.org/port-evbmips/2012/05/10/msg000132.html
  http://mail-index.netbsd.org/port-evbmips/2012/05/11/msg000134.html
  http://mail-index.netbsd.org/port-evbmips/2012/06/08/msg000142.html

I have not yet tried again since getting a working system running, but
hope to do so soon.
