The card has two ports: a standard DVI and an weird Apple port, which is a
DVI port plus power line AFAIK. The DVI port also provides analog outputs,
so I used a simple adaptor to connect the VGA port of the same LCD display
to the DVI port of the card.

That option actually makes things worse.

- DVI port: I can't see anything. The log below was taken with ReverseDDC=false
log: http://www.webalice.it/g_pochini/Xorg.0.log_DVI_noDDCrev

- ReverseDDC=false and VGA port: It seems to work fine. The initialization
issue I reported a few months ago is fixed ("flickering red channel").
log: http://www.webalice.it/g_pochini/Xorg.0.log_VGA_noDDCrev

- ReverseDDC=true and VGA port: Resolution is wrong (1024*768 instead of
1280*1024) and the monitor can't manage to display all the screen.

In all cases the mouse pointer is rotated horizontally by half its width.
For example: I see a "<>" in place of the X "><" cursor.
