I was talking about checking every 256 leaves from 0x40000000, but I
can't remember where I heard it.  The only relevant reference I can
find is the MS hypervisor interface spec's description of leaf
0x40000001: "Hypervisor vendor-neutral interface identification.  This
determines the semantics of the leaves from 0x40000002 through
0x400000FF"

Cheers,

Tim.
