: You could just use the same tunable for both drivers so it's perhaps less
: confusing and easier for users (they set the same variable for both ACPI and
: non-ACPI cases). I would vote for just 'hw.pci.host_mem_start'.
I made them different because I wanted to expose the tunable value as
a read-only sysctl. If I made them the same, I couldn't do that.
