If I was to guess; because Windows allocates MMIO space differently it 
hasn't been a problem.

Which begs the question; does Ilpo's series improve things enough that 
we wouldn't have these problems either?

Maybe we should just tail my patches on Ilpos' series and then land them 
linux-next the very beginning of next cycle and beg everyone who was 
affected to test linux-next.
