Some more info.

I have built and installed the latest git xserver and intel driver and the
xserver crash persists.  The trigger seems to be running the above xrandr
command while the TV is the only device connected (ie no VGA or TMDS-1).

Program received signal SIGSEGV, Segmentation fault.

(gdb) l
1186        /* sort by preferred status and pixel area */
1187        while (input)
1188        {
1189            i = input;
1190            input = input->next;
1191            for (op = &output; (o = *op); op = &o->next)
1192                if (xf86ModeCompare (o, i) > 0)
1193                    break;
1194            i->next = *op;

Any suggestions?

Also, can anyone confirm if they have ever had any of the progressive
component outputs working at all on the intel driver?  I suspect they are
just broken as nothing I do gets them going even when another display is
connected and running 1280x720 or 1920x1080.
