Well, it's really up to Jesse, but as far as I can see, this patch is a
net loss of functionality and doesn't actually add anything. Without
this patch, some resources that were not assigned by BIOS will be
unreachable. With this patch, *all* resources that were not assigned by
BIOS will be unreachable...

Apparently you're missing the point of the patch? The patch is needed
because BIOS is purposely not assigning I/O BAR's to devices that won't
use them, freeing up the resource for devices that do need them. Where
is the "all" resources that are not reachable?

Thanks,
Mike
