There are several problems I have with this patch:

1) What exactly is a `SUNW,Ultra-1-Engine'?  And what problem does it
have with that machine that this patch is supposed to fix?

2) The patch `seems to mostly work'.  What does not work?

3) The patch has not actually been tested on NetBSD.

Since you have access to that hardware and I do not, could you 
at least test it to the point you are confident it fixes the problem
you have on that haredware?
