I have no idea what you are talking about...

I sent you which values you should replace in the driver if you want
mapping which is incompatible with BIOS, with Windows drivers, with XFree
and with all singlehead configurations: Just replace output #1 source in the
matroxfb_g450.c::matroxfb_g450_connect with CRTC2 instead of using CRTC1, 
and you are done.

-  ACCESS_FBINFO(outputs[1]).src = MATROXFB_SRC_CRTC1;
+  ACCESS_FBINFO(outputs[1]).src = MATROXFB_SRC_CRTC2;


But then do not complain that analog output described as PRIMARY in the
matrox documentation displays CRTC2 and not CRTC1 (i.e. it brokes
all analog singlehead configs and thus consider it vetoed for stock
kernel).
