Okay - I'll apply it and wait for the screams if it breaks ;)

Yeah - I was thinking about this the other day and musing how difficult 
it would be to move SPARC32 over to ofmem. Not only would it help squash 
these kind of bugs, but it would also give Artyom a helping hand too.

I think I could probably do some of the work, but would struggle with 
the SPARC assembler for MMU entries and the I/O mapping in SPARC32. Is 
this something you think you'd be able to take a quick look at?


ATB,

Mark.
