Maybe not ideal (especially on 64-bit processors) it is more than possible to 
address a lot of memory (damn I forget the numbers, I think 64G).

Yes you can.  It will be slower than native 48-bit address modes from 64-bit 
processors, but not a large overhead at all (and the code mostly stays in 
cache).  You will need to select 3G/1G split to access the full 2GB you have 
in your system.  I have 1.5G and have to use 2G/2G to address all of mine.

That is a much larger benefit than most people give it credit for.  Almost 
double the registers!
