I think I probably asked the wrong question.  I should have asked: when will 
68030 MMU support be available in an official Hatari release?  I'd prefer 
Windoze, because that's where I'm currently running Hatari, but a version for 
Ubuntu derivatives would be fine too.

Well, my actual question was about Hatari.  The setup screen for selecting CPU 
type specifically says 68EC030+FPU, so I was able to figure out why a PMOVE to 
TC caused an exception.  Since the setup screen specifically says 68040, I 
would logically assume that the 68040 support includes the MMU.  But I had seen 
all the recent MMU discussion, which sort-of-implied that the MMU *wasn't* 
supported (at least until recent CVS updates).  So that's why I asked the 
question (and why I'm asking it again).
