Dataflash AT45DB161D and Arduino Leonardo

Okay so i've been trying to get the at45db161d with the leonardo for the past couple of hours using the library available in the playground and haven't had much luck with it.
After looking online i realised that the SPI headders are no longer populated with the DIO headers instead they are on the ICSP header I modified the library to use those pins instead pointing them to:
MISO - Digital 14
SCK - Digital 15
MOSI - Digital 16

Since SS pin is not brought out on the leonardo I initially tried using just a regular DIO pin in my case D11, which didn't work. Next reading online I found out that the SS pin can be tapped into using the via just on top of RX Led and pointing the code to use D17; that hasn't worked either.

I've tested the flash using an Arduino Mega (Mega1280) and using its SPI headers and the flash is working without any issues with the Leonardo it hasn't worked. Any Ideas?

Okay so i finally got the AT45DB161D to work with the leonardo. I used another library i found online http://blockos.github.com/arduino-dataflash/ maybe this can be helpful for someone else. The pageTest example in the library should work with little work, but i found it to be more geared towards uno and duemilanove. Below is a little sketch i wrote to test the Lenonardo. you can also download it from here Google Code Archive - Long-term storage for Google Code Project Hosting.
