I got a bunch of Gameloft games to work, by changing the build.prop to Galaxy Nexus. Same GPU as our tab, and high resolution, so the games should be optimized. Unzip this and overwrite the one inside /system/
Make a backup first, this might cause problems down the line.
EDIT: Yeah this kills sound. So, after you change your build.prop, download the games, install the data and restore your backed up build.prop. Sound will work again. The games will also still work.
There is an app on the market called "Device Spoofer" that makes this process easier.
