radeonfb / Radeon 9250 not detecting memory

All, I seem to be hitting a fit on PCI errors on this board. Was wondering if anybody could help me through this. Here is a condensed log of what happens when I boot 2.6.20-rc6, on a MPC8360E PowerPC. I have edited out all the extra stuff and left only what should be important. The ATI card is the 1:0b:0 device that gets mapped to IRQ 0x17 I have turned on and added some extra debug in the RadeonFB driver. Is there a common place reason why the driver can't detect the memory size?
