Lenovo Thinkpad Edge E530 laptop SD card reader not detected in Fedora 17

Hello,

I have been using Lenovo thinkpad Edge E530 for last two weeks with
fedora 17 installed on it.

$ uname -a
Linux maxico-lappy 3.5.1-1.fc17.x86_64 #1 SMP Thu Aug 9 17:50:43 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux
$

Everything is working with out any problem. But it's multi card 4-in-1
reader (MMC, SD, SDHC, SDXC) is not getting detected in Fedora 17.

lspci|grep -i mmc and dmesg|grep -i sdhc give nothing.

There could be below two reasons for it
        1. Hardware problem
        2. Fedora 17 kernel does not have latest driver for this
latest lenovo thinkpad edge e530 card reader


I tried in other lenovo thinkpad Edge E420 with Fedora 17 and it also
detects my NIKON D3100 SDHC card properly.

If anybody have faced this problem with Lenovo Thinkpad Edge E530
laptop SD card reader with linux, please let me know the solution of
this problem.
