Default Stereo emitter sync problem on Fedora 5 using 8756

I've installed the 8756 driver on Fedora Core 5, kernel 2.6.16-1.2096_FC5. The card is a NV28GL [Quadro4 980 XGL]. Everything works just fine, except stereo emitter synchronization (Stereographics E2). The image appears in stereo on screen and the emitter led lights when stereo is turned on, but the emitter is out of sync. When viewed through stereo glasses, the picture flickers badly and the stereo effect is way off.

We have various versions of the Quadro cards in use. Stereo sync works correctly on NV36GL [Quadro FX 1100] cards using this driver. Older NV25GL [Quadro4 750 XGL] (rev a3) cards are even worse than the NV28GL ones: the emitter led never lights. It seems the emitter gets no signal at all from the card. The GL window is drawn in stereo, though.

The stereo worked correctly on all of these machines using Fedora Core 3 (kernels 2.6.11 and 2.6.12 and 7xxx drivers).

I'm attaching output for the NV28GL machine.
