Your Princeton LCD "out of range" situation would likely be cured with the same procedure that drum
has followed here, except you'll add "1600x1200_60
" to the Modes line in your /etc/X11/xorg.conf
I think what drum
here did was boot with his CRT attached, to edit xorg.conf (perhaps in TTY mode, if X mode failed), and then reboot with his LCD to see if the config changes worked. You might have to do the same with your desktop PC. If you've already given your CRT to charity, then you could download and install a freeware add-on to Win XP which enables you to read/write files on the Linux partition, so that you could edit xorg.conf using Notepad or whatever.
BTW, is your "250
GHz" P-4 a prototype from Area 51?
