I've downloaded and installed XFree86 4.5.0 on top of the 4.3 install that came from the Netinst sources debian.uchicago.edu and debian.oregonstate.edu. I'm using the i810 driver FROM XFree 4.5, and the logs show the detection of the i915GM chipset.

All my "howto" searches have come up with Matrox dual-head issues, but not Intel. My XF86Config-4 is built based on other people's suggestions for Dell and Fujitsu laptops that I found in google searches before coming here.

Hi Robert. Possibly a couple of things in there.
I'm running Sid and I had a similar problem. I am not sure of the official XFree stance on this, but I found that moving the
Option "Xinerama" "true"
line into it's own section, like this:
Section "ServerFlags"
Option "Xinerama" "True"
EndSection
helped on my setup. However, you might also like to revise this line:
Screen 1 "External Screen" RightOf "LCD"
since you're actually listing 3 screens: 1, "External Screen" and "LCD".
Also, in your XFree.0.log (or whatever) a couple of interesting things cropped up. The following shouldn't cause too many problems, but you might want to revise the **Section "Files" ** part of your config file (for the fonts).
(WW) The directory "/usr/lib/X11/fonts/cyrillic" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/lib/X11/fonts/CID" does not exist.
Entry deleted from font path.
(WW) Open APM failed (/dev/apm_bios) (No such device)
However, the following *will* cause problems... it can't find your 2nd device.
(WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found
Also the following is telling us that the values you used for HSync and VSync are not the same as what your LCD monitor is reporting:
(WW) I810(0): config file hsync range 28-60kHz not within DDC hsync ranges.
(WW) I810(0): config file vrefresh range 43-100Hz not within DDC vrefresh ranges.
I would think your primary problem is the fact that it can't fine the device! Check using the "lspci" command (may need to be root for that). Note, however, that the values reported by "lspci" are in hex but the values in the X config file should be in decimal.
Hope that helps.
Grant.
