No, that sounds very much like a bug. Worth checking to see if we can
power down any other monitors from that machine. Can you file a bug (I
have a slight preference for bugs.fd.o) and attach d dmesg with
drm.debug=0xc for the powerdown sequence, xrandr --verbose,
intel_reg_dumper before and after dpms off.

I suspect that the registers will in fact be programmed correctly and this
will be quite a mystery to solve.
