Reason for closing: Fixed
Additional comments about closing: driver is working now with Xorg 1.12 - dualhead is sadly dead now.

I rebuilt the xf86-video-mga package with this and all problems were resolved, for me.
Yes it's also true on 32bit. Have the same problem. Going to try the patch.

I have video again, thanks!

Hey, so, remember back in the dark ages when dualhead was this
insanely wild differentiating feature? Matrox thought it was so
special, in fact, that they hid most of the implementation of it
(and a bunch of other stuff) in a binary-only blob called the
HALlib. As you'd expect it was pretty much a cut-and-paste of
the relevant Windows code, and then some open glue to keep it
working; clientlx.c is that glue.
I guess the theory was that if you don't tell people which
registers to duplicate to implement a second pipe in their own
hardware, they won't figure it out? A pretty eyeroll-worthy
idea even at the time, and definitely not something we should be
condoning anymore.
Kill it with fire ..."
I doubt if this will sit well with others who have dual head MGA adapters. I know it won't with me.. :(
