This sounds like a much higher priority problem than the two video cards problem. As a way to work-around it, maybe you should just use Marc's suggestion and disable the UMA device in the devicetree.
I wonder what the driver expects. Is it looking for the memory allocation at fixed locations? Do you have a register dump for the ATI device with coreboot and the factory BIOS before an OS takes over?
