I am using ubuntu 12.04 in my new Asus K55 (Intel® Chief River Chipset HM76). It works pretty well but the SD card reader is not recognized, and the Fn keyboard keys are not working. I have followed this link but it does not help.

Can you help me?
Thanks.

Here is the lspci output (for the not recognized card reader):
