Kyle, Justin,

First of all, thank you very much for your ideas.

The bad news: I noticed some irq conflict message in dmesg and figured
that moving the ATI to another PCI slot might help.  I think this
cleared up the conflict as the error in dmesg went away.  So, then I
specified (PCI:1:0:0) for the Nvidia and (PCI:2:1:0) for the ATI card. 
I tried the other Nvidia driver as well.  Nothing seemed to work and I
really can't afford to spend anymore time ($$$) fighting the Nvidia/ATI

The good news:  Here at work I found a computer in the closet with a
Matrox G450 dual head card. "Borrowed" it, popped it in and swiped some
config lines form the web and BOOM!, it works. :)

As Kyle would say, "now I'm cooking with gas"  meaning my primary work
box is now Linux and I've got my precious two monitors working for me. 
I also figured out the problem I was having with gftp not connecting to
FreeBSD.  The solution to that was to 1) use passwordless ssh keys and
2) specify the path on the FreeBSD box to sftp-server.

Thanks again,
