Where this 50ms comes from?
The McBSP2 FIFO length is:
Does Pandora uses 8Khz?
The same thing applies to the start_threshold as to the period size. It
has to be bigger than the FIFO size.

Defaulting this behavior would break other distributions for OMAP
platforms. I know, Pandora is bitten by this, but MeeGo, ubuntu, Linaro
is fine (as far as I know).
