Since video resolution is a parameter that is often stored in PRAM, leaving the battery out is not a good blanket recommendation. It matters not in the case of many Macs, of course, but video cards are apt not to like having no clue about what to do with a display. That seems not to be Lateralus's problem, true, but failure of an apparently-ready Mac to boot needs systematic consideration of all possibilities.
Lateralus: have you tried to reseat and bottom the PDS-style daughter cards? I take it that you are getting to raster, then, but not to on-screen pointer and mouse-tracking? The startup sequence is well-defined right through to the desktop, with quite specific 'milestones' such as those already mentioned. Where does your 9600 poop out, specifically?
Regardless of the lack of accompanying sound (if that is so), does an attempt to reset PRAM give screen blanking after the appearance of raster? Keep in mind that swapping CPU cards in and out is a good time to be using the CUDA instead of the four-fingered salute as the last action before closing the case. The CUDA in a 9600 is indeed a CUDA rather than a PMU reset button, so it needs 20sec or so to be sure of clearing parameters.
