Invert single monitor on dual display setup

[shadowwyvern]

I'm using Fedora 7 with an ATi X1600 Pro and the fglrx driver to run a dual display with Big Desktop enabled, spanning 2560x1024 over two monitors. Recently, I suspended the second LCD from a bedframe upside down and I'm looking for a way to vertically invert the output of the second display head to correct the image without sacrificing the Big Desktop functionality. Does anyone have any suggestions?

Most of the monitor mounts are designed to have pressure pointing down rather than pulling up. It may not be the most secure way to do this. It is relatively easy to make some C brackets to mount the LCD right side up.
