I think it's one of those little lapses that makes TOS so intriguing. Xbow seems to have chosen not to publish a full schematic, only the bits that changed from the mica2 when they added the different radio. So what's on that 2420 radio page is probably the best you'll find. I do remember something about the SPI lines needing to have pull-ups added in order to work correctly with external devices...
I'm just about to embark on my SPI learning curve so I can't pontificate, but I'd be surprised if there were timing problems due to hardware that behaves according to spec.
