I have 2 machines that are running 2.5.56 beatifully, except for fbcon 
and ISDN.
The laptop runs ATI radeon - when I attempt to boot with radeonfb+fbcon 
statically linked it wraps the pixels as if the driver is using 1410 
pixels per row while the hardware only has 1400
   

Can you try it with the latest code. I think fixes are in the standard 
tree for this.

Ok, I got some very good news. I found a workaround that lets me use 
rivafb+fbcon 99% ok.
I have a 1400x1050 LCD panel. When I boot with fbcon, it garbles the 
screen like it thinks the screen has 1450 or so pixels. I can't read 
individual characters, and the each line starts further and further to 
the right.
I can login and startx on the blind, here's an fbset output at that point:

mode "1400x1050-60"
    # D: 108.003 MHz, H: 63.983 kHz, V: 60.191 Hz
    geometry 1400 1050 1400 1050 8
    timings 9259 136 40 10 0 112 3
    rgba 6/0,6/0,6/0,0/0
endmode

The if I do an fbset -g 1280 1050 1280 1050 8, I can start seeing 
characters on the screen, here's the fbset output at this point:

mode "1280x1050-65"
    # D: 108.003 MHz, H: 68.879 kHz, V: 64.797 Hz
    geometry 1280 1050 1280 1050 8
    timings 9259 136 40 10 0 112 3
    rgba 8/0,8/0,8/0,0/0
endmode

At this point there's 3 problems:

1 - stty is still attempting to use 175 columns which would have been 
correct for 1400x1050 with a 8x16 font, but the screen is not set to 
1280, I do an stty columns 160 and that is now worked around.

2 - The cursor is gone, so I can't edit lines or run vi under fbcon.

3 - If I switch color depths, the code doesn't seem to be clearing the 
screen before rendering the new text, so I end up with 1 or more scaled 
down copies of the old text.

Starting to get useable here.

Now I'll test 2.5.58bk1 with tdfxfb+fbcon, I'll post more soon.

Thanks and I'll subscribe to linux-fbdev-devel so I can get posted on 
the updates,

Marcelo Pacheco
