	I am not near my server so these instructions wont be
	exact but you should be able to fill in the gaps or
	mistakes.

	First, go to the lts.conf file and put in the
	[default] section 'SCREEN_02   = shell' (without the
	quotes). and save it.

	Second, start one of the troubled cirrus PCs and when
	X fails, press Alt-Ctrl-F2 (or F1, I don't remember)
	to get to the prompt.

	At the prompt, type 'cat /proc/bus/pci/devices' This
	will give you a whole bunch of numbers. The numbers in
	the second column are pci ids. Copy the 8-digit number
	that starts with 1013. This is the cirrus card.

	Next, open up the vidlist file, its in the same
	directory as the lts.conf file. Go down to the cirrus
	section. Find the number you wrote down. Change the
	driver from whatever it says to 'cirrus'. Save it.

	Make sure your lts.conf file has 'XSERVER = auto' so
	the other 75% of the computers will work. Restart the
	troubled terminal and it should work.

	Last, and maybe the most important; if the troubled
	terminal works, it is now time to give back to the
	open source community! Please email the guy at the top
	of the vidlist file and CC Jim from LTSP and tell them
	about your discoveries. Ask them that your changes be
	included in the next release of LTSP. Be sure to tell
	them the version of LTSP your using, the pci id, name
	of video card if possible, and the driver you got it
	to work with. There are 100's of video cards in that
	file and not all of them have been tested with LTSP so
	your input is important!

	Chris
