Solution for me (MSI Neton AP1900 with Intel 945GM Display Adpater) was the
following:
- using vesa-driver
- modified /etc/X11/xorg.log
Section "Monitor"
Identifier "Configured Monitor"
HorizSync 30-100
VertRefresh 30-100
EndSection
I used the xorg.conf from Eric Griffis (thanks!):

No 3D (so no compiz), but resolution is correct now and the PC is in a
usable state, but this is only a temporary solution.
My guess, the 'magical' point is this (from /var/log/Xorg.0.log):
(II) intel(0): I2C device "LVDSDDC_C:ddc2" removed.
For this, I compared a working configuration with the same display
chipset (Samsung NC10 Netbook): /var/log/Xorg.0.log did not have any of
those lines. Probably, the internal screen is connected to the LVDS
channel, but because it is removed, hence not working, logically the
screen does not have input so stays black.
I tried Jaunty Alpha 5, but the problem still exists, despite status of
this bug "Fix released".
