PCI resources above 4GB

Hi Bjorn,

like many users here: 

https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-180/+bug/342926

I've hit this bug:
https://bugzilla.kernel.org/show_bug.cgi?id=10461

I was wondering whether an option to enable an algorithm which
allocated all 64bit capable devices above 4GB would at least allow
systems where the BIOS has not provided a sufficient PCI hole to
initialise all PCI devices?  I've been digging into the code, but I'm
not yet comfortable to seriously attempt this myself, certainly not
without guidance.

It's a shame TJ seems to have disappeared, it would have been great to
have had a look at his code, I'm sure many of these problems would have
been resolved.

Any help, workarounds, guidance or patches welcome! :)
