Dual Head with FC6 on Intel GMA 950

Dear all.

I am trying to get my Intel GMA 950 - which is in a Thinkpad T60 - running under
Fedora Core 6.
The Thinkpad-Display worked out of the box. Even the Desktop Effects are running
well. But now I have wobbling windows and a Cube of workspaces, but dual head is
still not running.

Trying to tell Fedora to start with both screens (the TFT of the Thinkpad and a
extern Benq FP 767 plugged to the Docking) by using system-config-display does
not  help. FC starts, like I didn't do anything, with only the LCD of the
notebook.

So I tried a mix of my humble xorg-conf-skills and some xorg-confs I found in
the net. (Thinkwiki, ...)

The result is, that FC starts fine at the first time, but I am not able to log
out and in again or restart X by typing CTRL+ALT+BACKSPACE. X won't start a sec
time. Here are some Errors of Xorg.0.log:
 > I810(0): V_BIOS address 0x7d8e0 out of range
 > I810(0): VBE initialization failed.
 > [..]
 > Backtrace: [...]
 > Fatal server error: Caught signal 11.  Server aborting
:q

There are some warnings in the logfile from the first start too:
 > (WW) I810(0): Bad V_BIOS checksum
 > (WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found
 > (WW) I810(0): Unable to estimate virtual size

Unfortunately I do not know what a V-Bios is, or what it does mean to Enabling
LVDS directly. Pipe B..

Has anyone any idea? May be some hints, a link to a good wiki, some working
xorg.confs?

Here is my xorg.conf:

the logfile of the second start:

thanking for any help
