AVR + nRF2401A

Has anybody succesfully used an ATMEL AVR (ATmega32 or ATmega128, or any other 40pin+ avr) with the nRF2401A or the uMIRF?

I am trying to run the system at 3.3v (the ATmega32L) using SPI (codevision compiler) and was wondering if the 10Kohm resistors on the App Note from nordic would be too much. I am asking this because I have no way of testing it before the board gets done (SMD all the way) and wanted to check if the 10kohm wouldn’t create a huge drop on the lines.

Thanks!!

PD: if you have any suggestions or other comments regarding the hook-up of the circuit, i’d like to know! thanks again
