Hmm. It's my understanding that it doesn't matter UNLESS the app uses chip-specific hardware (usually for performance in games).
Intel, for example, released an Android phone based on Atom and >90% of the apps worked with no tweaking. And this abstraction is a great benefit to using Java for your apps.
I think Intel's NDK software will port ARM to x86, as well. Intel's typically really good about developing tools to help get stuff ported to their architecture.
Netflix, however, is probably due to some hardware ties that prevent it from running on certain devices. Netflix runs on my Roku (Linux-based) and Android phone + tablet (Linux-based) but refuses to work on (or support) actual desktop Linux. I blame Netflix here.
That said, have you tried this? http://tinyurl.com/nflx180
