Right, the X58 variant of the chipset should be covered by
803075dba31c17af110e1d9a915fe7262165b213.  And it is, because we still get the
remapping warning when you boot up.  Whats odd is that you're still seeing the
issue, so there must be something else about your chipset that acting
differently than other X58's

chipsets in RHEL6.  You know everything there is to know in that bug :)
