sgolds,

My understanding of PAE is that it is just an API. It is not a change in the 32 bitness of the program. Nor it is a change in the fact that this program can address only 4 GB of data. THe API just cleverly shifts where the CPU is physically looking while addressing the same logical 4 GB of memory.

So there is no recompilation or anything like that. Recompilation, wile making changes to how pointers to data are handled is IMO extremely tricky, and it could be a recipe for a serious disaster.

Any tweaks in addressing capability of Prescott IMO would needs to be considered a brand new instruction set, not unlike x86-64 being a brand new instruction set.
