Hey Roger,

Unfortunately, I don't have them in a tree because my first patch was 
changed during merge, and also the tree was refreshed.  Basically, the end
result, we leave features enabled on linux side, thus setting not only
the cr0 bits, but also the cr4 PSE and PGE for APs (they were already
set for the BSP). 

Konrad only merged the CR0 setting part of my first patch, hence this 
patch to set the CR4 bits. Hope that makes sense. My latest tree is:
