I wonder whether there's an Atmel reference schematic around with an incorrect resistor value on it, the only three people I know affected by this are myself, Hein Tibosch and you, all on AVR32. We've now submitted one fix each, mine was similar to yours [1] but there's been movement on Hein's more comprehensive patch recently [2]. I don't know who's supposed to be merging MMC patches atm, Chris Ball added on CC on a hunch. --Ben.
