I then used xrandr on the system with the ATI card; I forget what I did

This sounds like something that isn't supported via the DVI/VGA cables or a
problem with support in the proprietary drivers.
The drivers could probably do the rotations, they just never got the proper
signal.  Having "Xinerama" enabled for the AMD
drivers really restricts what options you have, but duasl monitors didn't
work with AMD's driver any other way.
