Dual head problems

Hello, I have been trying to get multi headed support working with my
Dell Latitude C640 laptop, ATI Radeon Mobility 7500.  I have tried
everything that I have seen on the net by googling and can't seem to
find why it doesn't work.

I have tried both xorg's xinerama, and the radeon's pseudo-xinerama and
both give me the identical result, the same (cloned) screen on both the
laptop LCD and external monitor.

Attached are my conf file and xorg log.

Thanks,

Deric Abel
