Comment # 18 on bug 983532 from Oliver Neukum

Johannes, could you have a look at this?
The SD driver seems to have a problem with a device returning ASC 0x29.
I could work around this in the storage driver, but I think the device,
although unusual, acts correctly. Power on had indeed occurred. 
So this should be handled at a generic level.
