Interesting, I hadn't noticed the 4x3mm problem. I'm sure you're right
that this is causing the huge font.
I'm afraid the xorg.conf isn't very exciting - nothing more than the
defaults from the Xubuntu Live CD. I will attach it anyway.
Meanwhile, here is the more complete EDID info:-

I found an EDID format description here:-
http://faydoc.tripod.com/structures/01/0127.htm
I haven't tried to decipher the whole thing but the dimensions of 320x240mm are
exactly as reported in the Xorg.0.log.
The Modelines in the log look good but maybe the "fuzzy aspect match" is
misbehaving(?)
(II) intel(0): Using fuzzy aspect match for initial modes
(II) intel(0): Output VGA using initial mode 1400x1050
Between the correct probing of screen dimensions and the PIPEASTAT
warning, three modules are loaded: fb, exa and ramdac, but ramdac is
built-in so that narrows it down to two.
Thanks again for looking at this. If you decide it's not worth fixing I
won't complain. :) You'll notice I removed the serial# from the EDID, in
case I should get a sudden urge to abandon this lumpy CRT by an
interstate highway or launch it from a high window. [joke :-]
