Fam Fh Model DDR2 BKDG #32559-3.00 called it LockMovCr0.
Fam 10h BKDG #31116-3.00 (and beyond) called it AltMovCr8.
On sandpile I call it CR8D to reflect its intent: non-PM64 CR8.
Also, you cannot tell a #UD[LOCK CR1-7] from a #UD[CR9-15].
So the question whether a LOCK works for 1-7 = 9-15 is moot.
