Yes, it is hard to believe that such a design error is present in today SD 
cards. But spi mode is used only by some devices which do not have a SD host 
controller on board.

I know a commercial FAT/SD card software package, and I found that inside 
their spi driver, there is support for non-byte-aligned cards too. So I am 
not the only one who has knowlegde about this problem.

Should I send you one of these cards so you can verify this problem?
