Yea, the message popup doesn't seem to be working right now (possibly an issue with mdpi).. they'll probably fix it though
I've also read loose plans to have it popup after pressing something on the normal notification, so that will be cool.
Edit: Confirmed now
I've been able to get Google Now working slightly, and voice search works by bumming off 2 more apps. Just have to hit the search button after it puts it in.
Replacing QuickSearchBox with the above (where it says to replace GoogleQuickSearchBox) stops it from closing, then the 2nd app there (link here
since its broken on that thread) combined with the older Voice Search from the Play Store for voice searching
Voice input on the keyboard won't work though, and the Now app has some drawing issues.
Update: better apk with scrolling/drawing issues fixed here
Setting aGPS to mode 2 was a good choice - once it "settled in" (didn't have to wipe data), I think its much faster now
