Dual Head ATI Radeon Working Under XFree86

[Trevor S. Cornpropst]

Good news to owners of late model dual head ATI Radeon/FireGL cards.

I have an ATI FireGL X1 Workstation video card (dual DVI ports) now working 
under XFree86 using the latest XFree86-Server-4.3.99.12_2 from 
/usr/ports/x11-servers/XFree86-4-Server-snap. Note, this is a development 
snapshot of the upcoming XFree86 release, not supported by anyone :-)

The good folks at XFree86 have gotten the int10 stuff working properly so that 
both ports on dual head cards are initialized properly. Finally, my $400 
video card works, no thanks to ATI their Linux only drivers.

As Xinerama documentation is sparse on the 'net, I am including a working 
configuration, two flat panels attached to DVI ports, side by side display. 
Enjoy.
