I don't know Peter but these lines saved me and solved my problem !!!
If you want I can attach the two files !!! I've got the original one and the
modified xorg.conf.

Infact when I did't know about these modelines, I saw that my X was really
running even if I saw a blank screen...probably a problem caused by wrong
detected frequencies.

And I can add more...I've got an ACER AL708 and sometimes I got a similar
problem on the desktop. It's a LCD monitor !!!

I read your message:

>Thanks,
>but I've already read all relevant threads on that list and honestly: I
>dont understand why modelines should cause any effect on an LCD?!
>Weren't the modelines for CRT only? I thought they provide physical
>information (number of real pixels, time for the beam to return to the next
>line, etc.), but AFAIK LCDs refreashes all pixels at time?!

>Best regards,

And if I read this line:

# 1280x800 @ 75.00 Hz (GTF) hsync: 62.62 kHz; pclk: 107.21 MHz
 Modeline "1280x800"  107.21  1280 1360 1496 1712  800 801 804 835

I see informations about:
	- Maximum resolution
	- Maximum frequence
	- Horizontal Frequence

... I don't understand the problem you write about...because every monitor
has its own capabilities and LCD have its own FREQUENCY !!! Every pixel must
refresh !!! See this technical card  (it is right...excuse me for my poor
english) about a LCD 17:
