Public bug reported:

Issues created by upgrade to Karmic on Compaq C307NR laptop.

$ lspci -vvnn | grep -A1 "VGA compat"
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03)
	Subsystem: Hewlett-Packard Company Device [103c:30a5]

$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 4096 x 4096
VGA1 disconnected (normal left inverted right x axis y axis)
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 289mm x 21mm
   1280x800       60.1*+
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
TV1 disconnected (normal left inverted right x axis y axis)

As you can see, this is the typical misreported Intel screen size.
According to the manufacturer, the screen dimensions are 33.1 x 20.7 cm.
So, I have updated my xorg.conf with

Section "Device"
	Identifier	"Configured Video Device"
	Option 		"Monitor-LVDS1" "Configured Monitor"       <-- Line Added
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
	DisplaySize	331	207                                                     <-- Line Added
EndSection

And this successfully fixes the problems.

System fully upgraded from Linux Mint XFCE CE Gloria / Jaunty to Helena
/ Karmic.  Was working fine without additional xorg.conf tweaks in
Gloria / Jaunty, but upgrade to Helena / Karmic messed up the fonts.

Prior to fixing issue:
gdm was usable, but could not see what I was doing, as surrounding text was too large -- had to blindly type both userid and passwd.
     Once past the login screen, fonts normalized for splash screen leading to xfce.
kdm screen was navigatable, but all fonts, including typed userid and passwd, were enormous.
     Once past the login screen, fonts normalized for splash screen leading to xfce.
wdm looked fine, but splash screen leading to xfce still used enormous fonts.

Once inside XFCE, gtk applications seemed to go back to normal font
sizes.  All KDE applications were unusable due to enormous fonts, until
I changed XFCE to use custom dpi of 98 (as calculated by Xorg, after
forced DisplaySize added).  Even after XFCE tweak, some instances of
enormous fonts persisted in KDE applications until final xorg.conf tweak
added.

(Order of corrections -- added DisplaySize tweak in xorg.conf, forced
custom dpi in XFCE, added "Monitor LVDS1" option to xorg.conf)
