If you have aliendalvik or sfdroid, you can use Android's XServer-XSDL to run x11 applications as well, instead of using kwin.

With some configuring, it works roughly as well. On the plus side, It can do landscape mode and you can also use xrandr to rotate the display, but on the negative side, it doesn't pass through multitouch stuff, so chromium doesn't work quite as nicely.
