SDVO can generate interrupts, although a particular SDVO output type might not. (The G45 docs are missing this section, but the 965 docs are applicable.) We don't have that turned on, of course, because that would be entirely too sensible. You'd probably need to uncomment the #if 0'd intel_sdvo_set_hotplug() in intel_sdvo.c, and call that from the appropriate bit of intel_sdvo_init(). For pre-gen4 you'd probably also need to set SDVO_INTERRUPT_ENABLE in the appropriate SDVOx register, but in gen4+ that bit is used for bpc selection. Having done that you'd then need to wait the inevitable six months to find out which SDVO devices actually have functioning hotplug and which ones are just plain lying about it. - ajax
