Well in that case there are 2 things you can try. 

Use the code snippets I send earlier, even though it's not 
what you want, you will be able to see something happening
IF the hardware is not faulty. This code is used on a project
I'm working on currently where the M8 is talking to a GSM
modem and data is sent to a 68HC11 board via the SPI.


Change to mode 3 temporarily (CPHA and CPOL are one)
and use the low speed SPI mode. If it works then you can
try changing things and see where it fails.

Also make sure that the SS pin is set as an output so it doesn't
influence the SPI.

Don't know if I can do anymore as I know that you are quite
experienced, but sometimes just  talking about a problem will
show the answer. I talk to my budgies regularly and they are
quite IT savvy :-))
