Here is the incremental patch which should stick "strictly to the 
script" of ljmp immediately after writing CR0.PE.  This should be done 
to the boot code as well; I'm waiting for confirmation from the Elan 
original reporter before submitting that patch.

I decided to make this an incremental patch to make it bisectable versus 
the other one, however, it should probably be considered the right thing.

Note: I have not tested this beyond compilation, I'm afraid.
