Linux has no way to signal to the block device driver that it should flush
the write cache - so _no_ Linux filesystem can get it right, even on
disc drives with write caches. It's just more obvious with the large write
cache on the mtdblock device, that's all.
Linux is broken. Unless Linux gets unbroken and starts to deal with block
devices having internal write caches, the only option you have is to
disable the caching completely.

I thought you could write the ST flash in 8-byte chunks?
