X11 MGA driver and xrandr

[Steven Friedrich]

This system has been a dual-monitor since before the change-over from 
XFree86 to xorg.  The change-over resulted in losing dual-monitor 
capability, but I've recently taken another shot at it.  I knew I'd need 
to be patient during the change-over.

Both monitors are presenting the same desktop, not spread across them, 
just duplicated, which isn't useful. 8o)

The system is running 7.1p4, and latest ports, kde3.5.10_1. xrandr 
reports only one screen, Screen0.

Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1280 x 1024

I've tried running X without xorg.conf, with only ServerFlags Option 
AllowEmptyInput, and I even tried to use a Monitor section to force VGA2 
on. I don't know if the numbering starts at 0 or 1, but I've tried VGA1 
and VGA2, with Option Enable true. I have a Matrox G550 with a standard 
VGA connector and a DVI connector with the VGA adapter on it.

How do I get xrandr to recognize my second port.  Should I be waiting 
for a few more changes to MGA driver?

I'm not currently using mga_hal. I tried hal just now and it doesn't 
help.  Also, I noticed that when I use root to autoconfig X, it sets the 
driver to vesa, not mga, although there are MGA lines in xorg.conf.

Please don't tell me to get different video cards. 8o)
