Screen Resolution 1600x1200
To run the screen larger than 800x600, you have to switch off Framebuffer, and onto Vesa.
To do this you edit your /etc/X11/XF86Config file.
This worked successfully with Suse 8.1.
You can also run XF86Config, if you have it, and make sure to select Generic Vesa, as your display.
But if you are going to edit your file manually, here is a cut out of mine, you can copy as you will:
Section "Screen" #controls general res
DefaultDepth 16 #and colors
Section "Device" #specifies your device
Driver "vesa" #this is changed from
Identifier "Device" #original
Hope this helps, if you need more help. Just email me at email@example.com
One final comment: Suse 8.1 configured and installed all my devices except for the modem, and the screen. However, it is recommended you disable sound in the initial setup, and reenable it later since it tends to crash on first boot up after the install.
