Okay, great :)

I honestly don't know enough to make an informed choice, although my 
feeling is that since PPC has 512K (and it will obviously be enough to 
solve the problem with OpenSolaris) then it can't be too bad an option. 
Does anyone else have a feeling one way or the other?

The change to ofmem_sparc64.c is required to prevent an out-of-memory 
panic when starting OpenBIOS with a 512K Forth heap as otherwise the 
total amount of memory requested is too large for the ofmem code.


ATB,
