1 and 2 don't work. 3 and 4 do.

I put the logs here:

http://www.webalice.it/g_pochini/Xorg.0.log_conn1
http://www.webalice.it/g_pochini/Xorg.0.log_conn2
http://www.webalice.it/g_pochini/Xorg.0.log_conn3
http://www.webalice.it/g_pochini/Xorg.0.log_conn4

I noticed another issue: neither xvidtune nor ctrl+alt+KP+/KP- can change
the screen settings. xvidtune complains about invalid settings and it writes
this in the logs:

xf86CheckModeForDriver: called with invalid scrnInfoRec

I'm sorry, but the flickering red channel problem is still here. At least
now we know that it only affects the DVI output.
