Hi Chris,

Thank you very much for your prompt and clear answer.

However, I have two problems, if I may.

1.  On the 2.6.36.2 (the one I started this thread on),
 I always had ("just in case"):

    --- Direct Rendering Manager (...) 
        ...
          Intel I810                                                  
          Intel 830M, 845G, 852GM, 855GM, 865G                        
            i830 driver                                               
            i915 driver                                               
       [ ]       Enable modesetting on intel by default

For some reason, the boot parameter you suggested (grub excerpt):
        "kernel /boot/LFSkernel root=/dev/sda3 i915.modeset=1"
does not work.  The system remains "regular" (non-KMS), thus the
Original Post (problem)

2.  I tried your suggestion on 2.6.36.3 and 2.6.37 with
CONFIG_DRM_I915_KMS hard-wired.

The intel driver works perfectly in graphics now (i.e., problem solved)
Unfortunately, I end up with a situation where, in command (i.e., "VGA Text") mode,
I lose my long-beloved 80x25 full screen resolution and get _stuck_ with
something like 240x67 (1920x1080? ) - also full wide-screen
(the monitor is 16:9, DVI).

A grub line like
        "kernel /boot/LFSkernel root=/dev/sda3 i915.modeset=0"
clumsy as it may be, when I "know" in advance I'd be working in
command mode, does _not_ work.  The system boots KMS regardless.

Is there a way, once up in KMS, to "dynamically" switch to my old
"VGA Text" mode (from this crazy 240x67) and, ideally, back to KMS too?

Many thanks again,
