no, this is not an hardware conflict as the PCB is not still plugged on the CDB! Doing so i expected the kernel answers that the probe fails. But not an oops message..... the problem looks like a kernel configuration one. Isn't it?

The physical base adress 0x200003e0 should be available for you. The onboard Ethernet is located at 0x20000300 - 0x2000030f. Maybe you get some conflict's with that. As far as i can remember, is CS2 going low during access to the Ethernet chip. So you have to decode this ! Can you use a different CS line like CS3,4,5 or disable the ether driver for a test?
