Sure, see below.

  #!/bin/sh
  #
  # tvout
  
  # needed for G400 only
  #modprobe -k i2c-algo-bit
  modprobe -k i2c-matroxfb
  modprobe -k matroxfb_crtc2
  modprobe -k matroxfb_maven
  
  matroxset -f /dev/fb0 -m 0 # this disconnects fb0 from outputs 
  matroxset -f /dev/fb0 -m 3 # this connects fb0 to both outputs 
  matroxset -f /dev/fb0 -o 1 1 # this sets fb0 to PAL output 
  
  #fbset -fb /dev/fb0 -xres 800 -yres 600
  
  fbset --all -fb /dev/fb0 640x512-52
  
  # 800x600 mode set via kernel command line parameter
  #fbset -fb /dev/fb0 800x600-60

The videomode 640x512-52 is configured in fb.modes like this:

mode "640x512-52"
    # D: 25.175 MHz, H: 32.442 kHz, V: 51.907 Hz
    geometry 640 512 640 528 32
    timings 39722 60 0 70 39 76 4
    bcast true
    accel true
    #rgba 8/16,8/8,8/0,8/24
endmode

the tvout script is run before the iv script (see below) during bootup.
Note that i start X manually with startx from a console.
