I can report this as well, though in my configuration it is a laptop
with a Quadro FX770M chip. The laptop display will resume from a power
save, the attached external display (via DisplayPort) does not. After
power cycling the external display, visibility is restored, but it's
extremely aggravating to have to repeatedly power-cycle that external
display.

I saw a note in one of the later nvidia drivers that they resolved a
power-save problem with DisplayPort attached devices, though I don't
know if this is related.
