I`ve added the X11 modeline to the 'modelines' file and
rebuilt the
'videomode.c' file and the kernel.

And it works! After radeonfb initializes, the monitor sets
up in 1024
x 768 mode at 89Hz.

But there is still a problem: although the monitor is set up
correctly, the driver thinks it's still running at 640 x 480
resolution mode, and so it creates a 640 x 480 display:

radeonfb0: display 0: virtual resolution 640x480 at 32 bpp
radeonfb0: port 0: physical 1024x768 89Hz
radeonfb0: port 1: physical 1024x768 89Hz

So it creates a small box of 640 x 480 pixels at the left
edge of the
screen, and the rest of the 1024 x 768 space is not used (it
appears
filled with a blue-ish color).

The patch for the modeline:

I can post here the full dmesg if it's needed.
