Yeah - so it depends on which motherboard you have.
The PXA255 (basix and connex) have all 4 serial ports.
The PXA270 (verdex) doesn't have an HWUART, however, for backwards
compatability the BTUART pins on the PXA270 processor are connected to
the same spots that the HWUART pins were on the 60 pin connector.
So the fact that you only see 3 ports initialized suggests that you
have a verdex. The wiki was written with respect to the basix/connex.
