Solution of: Not using mode "1280x800" (no mode of this name) i810

Finally solved!

I have spent more than two days now on solving following Xorg error:

Not using mode "1280x800" (no mode of this name)

When browsing the /var/log/Xorg.0.log i found that the actual found
resolutions was multiplied by 4 and that there wasn't any resolution
found for 1280x4.

After two days passed I went to visit wiki.x.org where I found an edit
made stating that bu running 855resolution 4d 1280 800 once before
running X.

I tried to do this and it worked like a charm! Yippey!

Finally I wrote a startup.sh script contaning this and added it to
runlevel 5.

It now works for me!
