Andy made some fixes too the SD code a few weeks ago and these went into
his stable tree, but that was only available from the openmoko unstable
repos. I don't know if the fixes have progressed into testing or stable
yet, but if you aren't using a kernel with them you should give that a
try. I'm not sure how to tell which kernels have the patches though.
