Red Hat 7.3 and Dual Monitor

Hi

i've a physical host computer with Windows XP Professional Service Pack 2 and 2 video card ATI configured with 1280x1024 resolution for each card and with desktop extended on second monitor.

In VMware Workstation 8.0.2 build-591240 i have guest system:

-- Linux Red Hat 7.3 (kernel 2.4.18-3) with installed and running VMware tools.

-- Xfree86 version 4.2.0

My problem is that i want use dual monitor in guest system but it not work!!

In Virtual Machine preferences i set "Use Host Setting" for display. But when i click on "cycle multiple monitors" when i'm in full screen mode, i receive the message:

This virtual machine cannot use multiple monitors for the following reasons:

     -the virtual machine must have up-to-date VMware tools installed and running

This is my XF86config-4 file:
