How do I access nvRAM from user space?

Sorry for the dumb question, I just can figure out the right google search 
to find what I'm trying to do.  I'm running 2.6.27-rc4 on an mpc8347 with 
a 32KiB nvSRAM (Cypress CY14B256L) on the local bus.  We just want to be 
able to access this memory from user space seperately from "main" memory. 
We've got a process that needs to be able to remember info through power 
cycles.  Can anyone point me to an article or some code snippet that does 
something like this so I can sink my teeth into it?
