Problem Description:

Using the actual radeonfb kernel driver with a X800 videocard gives me a black screen of the death and will crash xorg. Worth, with the vesafb driver the card is not even working well.

Also, i gathered some patches that were published on the fbdev forum, and changed few easy things to make the driver understand the monid ddc type of the videocard and print better kernel messages. I tested the vga ddc and the monid ddc and both are working well.

The only difficulties are, first i need to deactivate some options in xorg.conf to be able to switch back and forth to the virtual ttys.

[code]

        Option      "IgnoreEDID" "off" 
        Option      "ReverseDDC" "off"
        Option      "VGAAccess" "off"

[/code]

Second, the driver needs to share the same resolution and color depth as xorg.

The following options are working with the radeonfb framebuffer. I have only tested them when the radeonfb driver was compiled like an optional module.

options radeonfb mode_option=1680x1050MR-32@60
options radeonfb ignore_edid=0
options radeonfb ignore_devlist=1 force_measure_pll=0 nomodeset=0 noaccel=0

I hope these patches will help radeon X800 owners to have a nice splash screen on their flat wide screen... but without guaranty. My knowledge in videocard logic is quite thin :)
