That MacModel option just hardcodes connector tables the same way the ConnectorTable option does.  It's just easier to specify the mac model than to specify a ConnectorTable string.  I doubt they will be useful in your case, since they are just arbitrary combinations of encoders, connectors, and ddc channels corresponding to a specific machine which may or may not be similar to your particular board.

O.k., I now tried to use one of the half-way working "MacModel" options plus a hard-coded monitor modeline as in the good old days, and now I at least *have* an output in 1280x1024 with the accelerated driver!  However, there are still several issues:

- Switching to a text console doesn't work.  Hit <crtl><alt><f1>, and the well-known green shades/blue line appear.  Switching to any other console or back to X doesn't work, no chance to get video working again but a reboot.
- Only XAA acceleration works properly; with EXA some colours seem to be "mixed" or "missing" (like less red and more blue) resulting in weird icons.  Maybe a different colour order?
- Both Xine and VLC show an effect as if the pixel order is reversed (like a PowerPC/endianess issue) if Xv output is used.  The ssllooww X11 video output on VLC works properly.  This effect is not present with the frame buffer driver.
- In the Xine splash screen, I see two thin lines of very bright, flickering green pixels.  never saw that before.

Any ideas?

Thanks,
Albrecht.
