Just for reference: I found the problem.
My architecture does not supports to change the resolution so when the
Xorg or Xfbdev tries to change it I get the error.
Here is a similar thread regarding this problem and showing a workaround
to solve it:
http://www.mail-archive.com/x...@lists.freedesktop.org/msg04115.html
I got an old version of xfbdev that works for me and when I use strace I
can see that it does not call ioctl to send FBIOPUT_VSCREENINFO command.
Now I will try to compile Xfbdev applying the mentioned workaround.

Hi!
This is my first message to this list. If I did anything wrong, please
advise me!
I am new here, I work in a brazillian company and we design boards
using ARM CPUs.
Now I am trying to start Xorg using the framebuffer in our custom
board based on the i.MX27 ADS from Freescale.
We are using Debian Lenny and had installed all Xorg from apt-get and
the system is updated.
We are using kernel 2.6.22.
When I run startx, it ends showing the below message:
(EE) FBDEV(0): FBIOPUT_VSCREENINFO succeeded but modified mode
(EE) FBDEV(0): mode initialization failed
Fatal server error:

giving up.
xinit: Connection reset by peer (errno 104): unable to connect to X
server

In the /var/log/Xorg.0.log:

All this modes that X is testing was declared inside the xorg.conf
because when they are not there I always receive the error message
"mode not found" instead "test failed".
