port/sparc64 known working on Netra X1?

[Chris Ross <cross+netbsd%distal.com@localhost>]

  I have a Netra X1 that I'm trying to get NetBSD onto.  I'm netbooting, which 
may be some of the problem here, but I don't suspect that right off of the bat.

  The kernel gets loaded from the NFS root, and begins to run.  Then, 
while/after attaching psycho0, it seems to just hang up pretty hard.  A break 
doesn't have any effect.  I'm using the serial console, so it's possible also 
that the kernel is messing that connection up somehow, but I don't see that 
happen on other sparc64's, so.

  Does anyone have a Netra X1 (of the same class as the one below) running 
NetBSD?  Just to verify that it *should* be working...

  Thanks.  kernel messages, that there are, are included.

                              - Chris
