For setups that worked fine, the only expected change is a possible
little different BAR layout (in /proc/iomem), and there should the same
quantity (or more) of BARs assigned than before.

But if there are any problematic setups, which weren't able to arrange
new BARs, this patchset may push a bit further.

In a few days I'll provide an updated branch for our mirror of the
kernel on Github, with a complete and bumped set of patches, reducing
the steps required to test them.

Thanks!

Serge
