Just tested with multi-touch test app, its definitely device bug (i hope its software). The points keep inverting
Moved a/b/x/y to top-right position, it helps a bit (menu problem is gone) but from time to time down+b registers as up.

Let me rephrase that again, up + b acts like x button (in many games its in-game menu or map).

You misunderstood us, we are talking about games menu not emulators. It happens not only in chrono trigger but in zelda: link to the past.

I have excatly same problem, up + b always opens menu. I'm using HTC Desire with android 2.2. And yes, on-screen controls are in the default layout.
