SRU justification:

Impact: The MMC controller on the ricoh chipset has to be disabled in order to 
enable the MMC cards to be detected by the generic driver. This fails on newer 
chips since the wrong PCI function is used to perform the operation.

Fix: Patch from 2.6.29rc2 which adds the required restraint.

Testcase: Card insertion without the patch results in no detection. With that 
patch it is detected. (Got a test in the report with an older chipset which 
still worked.)
