GeForce 4 with FCP and Cinewave

I recently upgraded my machine to OS 10.2.3 and installed Cinewave RT 3.0 to find that I would get a Kernel Panic if I had more than 1 Gb of RAM and two seperate graphics cards. I have taken out my second video card (an ATI PCI card) and retained my RAM to get the system to work, which it does. I would like however, to get a card that can run two monitors. What is the recommended card to get? Right now I'm looking at the GeForce4 Titanium Graphics Card Kit. What's the right dual card to buy for use with Cinewave?

Here is my setup:
G4 with dual 533 processors, 1.12 Gb of RAM
128 mb RAID
OS 10.2.3

Two Hitachi CM715 monitors
Cinewave RT 3.0
FCP 3.0.4
Pro Analog BOB
Pro Digital BOB

Thanks,
Tim
