[Card you described...]
That's it.
I tried swapping the RAMDAC chips, and now I have a different behavior.
The screen is all blue. Nothing at all.
Swapping them back, now my origional ramdac gives no signs of working.
No signal at all. Switch them - all blue screen. Something's seriously
wrong with the other card, it toasted the ramdac I put in it...
(And YES, I checked orientation before applying power.)
