ATI and multiple displays

[Daniel Corbe <dcorbe@xxxxxxxxxxxxxx>]

I have 2 video cards in this machine and I'm trying to use them to drive 
a multi-display setup.  I can't quite seem to get it to work.

I've attaced the output I get when I start X (file: blah) and my XF86Config

Any help would be appriciated
Thanks!

# To customise the XKB settings to suit your keyboard, modify the

# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
# Or if you just want both to be control, use:
