There has be some patches on the lkml list for the creation of a SPI  
layer similar to I2C.  I'm not sure what the latest status is.  I'd  
google search for SPI on lkml.

Once something like that gets in I'm sure someone will get around to  
contributing a SPI driver for the 82xx line of processors.
