What Binyamin is referring to is that CR5 contains the address of the ASTE for 
the home address space. 

The ASTE contains all sorts of cross-memory info used by the PCAUTH address 
space. If you are feeling masochistic you can try hunting down the various 
pointers and convert addresses between real and virtual and you will probably 
eventually end up somewhere with PCAUTH looking at some obscure control block.

If you are looking at a dump - it is much better to use IPCS to format the data 
for you.

If you want to find out this information from within a program then things get 
more (ahem).. "interesting"
