BIOS normally programs device BARs to valid values, and those values usually end up in resource[N]. But sometimes Linux decides the BAR values are incorrect, and it sets start = 0x0 to indicate that. If you can boot a current PCI linux-next kernel, we recently added a little more debug output, and maybe that would give more clues. Please post the whole dmesg log if you can try this.
