In Herve's guide, he mentioned that the buttons are not working.
It's the kext's lack of support, you'll just have to wait for the developer to add more support.
Not working:
RTS525a microSD card reader
Touchpad buttons
TrackPoint
ACPI files are already patched with the hotpatches/SSDT's.
For Bluetooth, did you add BrcmFirmwareRepo.kext & BrcmPatchRAM2.kext?
It's all in Hervé guide you linked on the 1st post
