	As I said, neither has a graphics card, and I certainly have never
seen an Intel motherboard with an AMD GPU.  I would think the execs at Intel
would rather have their nards shredded than use an AMD product on one of
their motherboards.  Come to think of it, however, would the GPU or its
drivers even have any effect on XDMCP?  I'm not an expert on X11, but I
don't think X11 makes use of any local GPU resources - hardware or software
- when the X-server is remote, does it?  That, along with the fact the GPUs
are as different as can be would seem to tend to eliminate the GPUs or their
drivers as the source of the issue.

	That said, on a note related to the Intel GPU, I did have to disable
the i915 modeset in /etc/modeprobe.d/i915-kms.conf on the Pentium system or
else it would not boot without a monitor.  As I recall, the video driver
installed by Debian is xserver-xorg-video-intel.  (Oh, BTW, I mis-spoke a
bit:  It's a GX-260, not a GX-1.)

	On what I don't think is a related note - but could be - KDM does
not come up on the console of the AMD machine.  The console never switches
to the graphical interface.  I'm not sure why, but since I never use the
console, I really haven't worried about it.  I don't recall exactly when
this broke.  I don't think it was during the upgrade to "Squeeze" / KDE4,
but I could be mistaken.  It definitely worked under "Lenny", however.

	I don't follow.  The embedded controller on the Asus MB is a Radeon
HD 3200, though.
