i think this should be s/mode/level/

"the forced DPMS level" or "forced DPMS levels". 
also, no comma before 'and' here but that's being anal.

this is probably in line with the rest of the document but it seems odd to
specify the length of the request (2) but just CARD32 for the length in the
reply (instead of 0). especially since the first 8 bytes (including the
length field) in the reply are fixed anyway.
