DVI->ADC 22" Cinema Display via KVM doesn't work

["Paul J. Lucas" <pauljlucas@mac.com>]

	I just installed Debian Linux (sarge) onto a Mac Mini (kernel
	2.6.8).  I want to share a 22" ADC Cinema Display between it
	and another DVI Mac running Mac OS X.  I have a
	Compucable/AddLogix Bi-System DVI to ADC KVM box.

	The KVM works fine for the Mac running OS X, but it doesn't
	work for the Mini running Linux -- the screen is blank and the
	keyboard/mouse don't work.  (The keyboard/mouse are plugged into
	the back of the LCD into its USB hub.)  There's also a Belkin
	6-in-1 USB media card reader plugged into the other USB port in
	the LCD hub.

	When I switch the input from 'A' (Mac OS X) to 'B' (Linux), the
	light on the card reader goes out.  If I press a key, the light
	comes back on (and stays on).  The red light under the mouse
	doesn't come on except if it's clicked -- and then goes back
	off.

	If I look in /var/log/messages,, everything looks OK, i.e, there
	are messaging saying how it found a USB hub (in the LCD) and
	the mass storage device (the card reader).

	After some searching, I found this:

	for FreeBSD.  Has an equivalent patch made it into the Linux
	kernel?

	Any other suggestions on how to get this to work?

	Note: I don't particularly care about have X11 work.  I really
	just want the LCD to display the text console.
