The xf86 mode setting code was mis-using this field to try and store a pointer to a DisplayModeRec, however, each output has its own copy of every DisplayModeRec leaving the one in in the RRModeRec devPrivate field pointing at a random DisplayModeRec. Instead of attempting to rectify this, eliminating the devPrivate entirely turned out to be very easy; the DDX code now accepts an arbitrary RRModeRec structure and set that to the hardware, converting it on the fly to a DisplayModeRec as needed.
