I know, it's still on my growing todo list... I didn't find clean solution I just use dirty hack that shoot of the 4GB MTRR entry overlapping LFB.
And this may happen even on systems with 4GB only (some use remapping of the rest of 4GB above 32bit barrier)- if you look at logs you will see that it happened in this case (there are 2 logs before and after enabling WC for LFB).
