Sort of.  It supports the S/390 G4 and higher.  Doesn't support the S/390
G1, the ES/9000, or others.  Basically what I am doing is to move all the
code for the S/390-Ri4+ instruction set onto its own compiler flag.  
Finding exactly where all these instructions are is taking time.  It'll
take me another month or so.  When I am done, though, I will be able to
get the NetBSD kernel working on any IBM mainframe newer than the ES/9000
9021, and maybe even older systems than that.
