This used to work, but revision 1.544 of src/sys/i386/i386/machdep.c moved the code that mapped in those pages until *after* they need to be used. I (unsuccessfully) petitioned the committer who made the change to revert it, so for now you'll have to manually remove it, being careful not to step on the changes introduced in revisions 1.545 through 1.547.
