That means that having a single ROM BAR that is 32-bit and prefetchable will downgrade the entire window to 32-bit ? That's not going to work either. I have GPUs with 16G BARs for example... suddenly they don't fit anaymore because we downgraded the window to 32 bit because somewhere there's a 32-bit pref resource ? That will break more than it fixes...
