Noticed new posts in this thread only today. SD card speed result above is twice as slow since there is no high speed SD mode in my kernel (only high speed MMCplus mode which is different). I have SD high speed mode enabled as part of my unreleased SDHC kernel. Will post some testing version soon. Check this thread for possible progress.
