I did the port to NetBSD quite a while ago, and did some mild testing.
Things seemed to work, though I had to do one strange workaround. 
Some time went by, I updated the code to -current. Some other people
tested it, and noticed a few problems. These need to be worked out,
but I haven't had time to look in detail yet what the cause could be.
The bugreports I got were fairly detailed, though, so hopefully
it'll be resolved soon.
