First:  I _really_ appreciate your help!

I added 8086A010, 8086A011, and 8086A012 to a file 
/usr/share/xserver-xorg/pci/intel.icv, and then I get:

    (EE) Failed to load module "i810" (module does not exist, 0)
    (EE) open /dev/fb0: No such file or directory
    (EE) intel(0): No kernel modesetting driver detected
    (EE) Screen(s) found, but none have a usable configuration

So, I went back to /etc/modprobe.d/i915-kms.conf and set 'modeset=1'
(was 0).  When I do that, the Console initializes and uses a
framebuffer (which looks nice)... but when X11 starts is garbles the
screen and makes the virtual terminals unusable (like when vsync or
hsync is wrong).  I think the error messages are the same, too.

This suggests that I'm missing a kernel module, right?  What would
it's name look like?

How can I confirm?  I'm actually using Debian/experimental's version
of 2.6.33.
