How well has this been tested?  I recall that there was some reason I
did this, like the DMA wouldn't work to unaligned addresses.  Or would
show up in the middle of the buffer if you read from an unaligned
address.

So has this been tested by trying to read a partial block?  By trying
to read multiple blocks that start and/or end at non-block-aligned
addresses?  I can't test this tonight, but will this weekend.  I hope
this didn't break it.  :)
