Um. Don't look the screen into landscape. WTF. Just don't. On some hardware you may get different performance in different orientations. Looking into landscape isn't a magical fix, it just pisses off your users.
There are optimizations on Tegra 2 that can be done when the screen isn't rotated from its natural orientation (which on the Xoom is landscape, but that is just the Xoom and other Tegra 2 devices may use portrait as their natural orientation). In this case I believe that overlays on Tegra 2 can't be rotated, so when in the natural orientation they can be used for window surfaces but can't be used in any other rotation.
