Can you also show the contents of /proc/iomem?
It does look like it's this one:
pci 0000:01:00.0: BAR 0: can't allocate mem resource [0xe0000000-0xe7ffffff]
and the problem is that the kernel cannot find enough space to map the required 128MB region for the graphics aperture.
Which is really odd, because the bridge to that PCI bus#1 is this:
pci 0000:00:01.0: PCI bridge, secondary bus 0000:01 pci 0000:00:01.0: IO window: 0x9000-0x9fff pci 0000:00:01.0: MEM window: 0xf0000000-0xf1ffffff pci 0000:00:01.0: PREFETCH window: 0x000000d8000000-0x000000e7ffffff
and that prefetch window is _huge_. Certainly big enough to fit BAR 0, but maybe there is something else in it.
