Large mmio resources and 4G+ of RAM...

just FYI, making BARS live above the 32-bit limit will break every single
linux cluster here at LANL, and will also disable Plan 9.

With BARS under the 32-bit limit, you can boot anything. With BARS above 
that limit, you immediately limit what you can boot. 

I think what really ought to happen is we fix linux early boot to do what
we wanted in the beginning of this project 5 years ago: linux should do
BAR optimization for the kernel that is running.

In principle, I like your BAR fix, but setting up BARS that are optimized
for 64-bit kernels should be a (normally disabled)  option.

I wonder if we can put BAR reallocation into a payload?
