I can't get the i915 log unless I remove th nvidia card.  I'm not sure this is 
worth trouble shooting.  It isn't to me, but if you want me to, I'll do it.

It's a flat panel, but it uses a standard 15-pin VGA connection.

I don't know what KMS is.  The system is a stock LFS-6.5 with a kernel. 
  I don't know how fast they develop.  If you mean Keyboard-Mouse-System,  what 
I have now is:

(WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' 
will be disabled.
(WW) Disabling Mouse0
(WW) Disabling Keyboard0

and later:

(**) USB Optical Mouse: always reports core events
(**) USB Optical Mouse: Device: "/dev/input/event3"
(II) USB Optical Mouse: Found 3 mouse buttons
(II) USB Optical Mouse: Found x and y relative axes
(II) USB Optical Mouse: Found scroll wheel(s)
(II) USB Optical Mouse: Configuring as mouse
(**) USB Optical Mouse: YAxisMapping: buttons 4 and 5
(**) USB Optical Mouse: EmulateWheelButton: 4, EmulateWheelInertia: 10, 
EmulateWheelTimeout: 200
(II) XINPUT: Adding extended input device "USB Optical Mouse" (type: MOUSE)
(**) USB Optical Mouse: (accel) keeping acceleration scheme 1
(**) USB Optical Mouse: (accel) filter chain progression: 2.00
(**) USB Optical Mouse: (accel) filter stage 0: 20.00 ms
(**) USB Optical Mouse: (accel) set acceleration profile 0
(II) USB Optical Mouse: initialized for relative axes.
(II) config/hal: Adding input device Dell Dell QuietKey Keyboard
(**) Dell Dell QuietKey Keyboard: always reports core events

One thing to mention is that the problem I saw on the graphics screen was a 
completely black background and no X cursor when I did:

Xorg -config /root/

Now that I think about it, I think I saw the same thing with the nvidia card 
(but no FATAL message).  I then tried startx and it worked.  It's possible that 
trying startx with the i915 driver might have worked, but I never tried it.
