It's pretty well broken in the official 4.3.0 sources and in our tree.  I'll 
try to send-pr the errors I'm getting in alpha_video.c.  Some of the errors 
are pretty basic and include missing brackets (!) and mislabeled NetBSD 
includes, and subroutines that refer to variables initialized in code that 
NetBSD doesn't touch using our rules (e.g. bsd_axp.c isn't compiled, but 
contains variables referenced in alpha_video.c).

I don't know if anyone else has had better luck with this goo, but I think I'm 
close to getting things linked.  If I can make this dog bark I'll report my diffs.
