Whoa... there isn't _any_ iomem free and available to use below 0xffffffff.
And IIRC that's the upper limit for use by the Cardbus bridge. Therefore, we
can't allocate a memory window, which is needed to read out the CIS ...

Now, I have no clue at all on how to reduce the iomem usage by other
devices... maybe linux-pci can help in this regard? Or twiddling with some
BIOS settings?

Best,
