Well it does improve that situation in so far as the card is unusable
in my system without these changes. Without lowering the fifo trigger
level (but with the other changes) I got it working but occasionally,
especially when using the USB bus, I still got fifo overflows. With
the lowered fifo trigger level that's gone.
