Depends on whether you are dealing with "regular" PDF or PDF/X (or A or E).
 In the case of PDF/X (A/E), DeviceGray is to be treated as the K channel of
CMYK.  So that simplifies you back to just two.  For regular PDF, you can
pretty much treat it any way you want that makes sense for the output
device.
