vesa/mga driver problems upgrading to FreeBSD 8.0

[Dan Strick]

I just upgraded my old backup system from FreeBSD release 6.1 to
FreeBSD 8.0 and I am having a terrible problem with X11.  My graphics
card is a Matrox Millenium II and it worked just fine with the mga
video diver.  The mga driver seems to have gone away and the Xorg server
insists that I use the vesa driver.  The vesa driver does not seem to
recognize any video modes with resolution greater than 1024x768 which
is just not acceptable for general use.  The only obvious documentation
for the vesa driver, the "vesa" man page, does not list the acceptable
video modes or suggest where such a list might be found.  The Xorg.0.log
file it produces lists a bunch of "DDC gathered Modelines" such as:

(II) VESA(0): Modeline "1152x864"x0.0  108.00  1152 1216 1344 1600  864 865 868
900 +hsync +vsync (67.5 kHz)
(II) VESA(0): Modeline "1600x1200"x0.0  175.50  1600 1664 1856 2160  1200 1201 1
204 1250 +hsync +vsync (81.2 kHz)
(II) VESA(0): Modeline "1600x1200"x0.0  162.00  1600 1664 1856 2160  1200 1201 1
204 1250 +hsync +vsync (75.0 kHz)
(II) VESA(0): Modeline "1280x1024"x0.0  135.00  1280 1296 1440 1688  1024 1025 1
028 1066 +hsync +vsync (80.0 kHz)

but when I try to use one of these modes the driver claims that there is no
such mode, for exaple:

    (II) VESA(0): Not using mode "1152x864" (no mode of this name)

and it seems that the driver simply ignores any modes that I define.
I guess that is a vesa thing.

Are there any VESA modes with useful resolutions?
Is there any way to get the old mga driver back?  The port builds ok but
will not install because some other driver that it depends on is broken.
