   }-But the sun4m port is actively being worked on and there has been some
   }-substantial progress over the past few months.

   Out of interest ... What exactly have been proven to be the problems with
   porting NetBSD (or mach or any other os) to sun4m?

At the very least, non-availability of documentation.  Also the
non-disclosured nature of the sun4m architecture specification
although most of what is in there can be easily reverse engineered and
learned through trial and error but this takes time.
