Yes, details of the necessary patch are posted in the thread dedicated to that matter; you'll find it in the Technical info/R&D -> Card readers section. It applies to all versions of OS X/macOS that the Sandy Bridge E6x30 laptops may run. Process could not be simpler:

  1. identify your card reader location in IOReg
  2. inject the necessary property in the Device Properties section of your bootloader's config

 

For instance, if your card reader is under RP0x@1C,5->PXSX@0, your property patch would be:

Device location: PciRoot(0x0)/Pci(0x1C,0x5)/Pci(0x0,0x0)
Property key: compatible
Property value: pci14e4,16bc
Property type: STRING
