Right, looks like a longstanding bug in that glue. So IMO, no rush to fix for 2.6.29-rc ...

Easily tested with a Beagle or SDP though, if you have a 1.8V or dual-voltage card (maybe RS-MMC, as for an N770 tablet).

Well, two patches for sure; I don't know that the order will matter. I just sent a patch fixing that code in the current OMAP git tree, which has some fixes that are scheduled to merge for 2.6.30-rc.
