Those precompiled libraries for LWJGL are for x86, not armel. (Check them with "file", and you'll know.)
That's the main problem about it. There is GLES 2.0, but no armel around. If we do find them, we simply replace the libraries for Minecraft.
But furthermore, as I see it, there might be some differences between using GLES and GL. I'm not sure if it will work directly, but I think we'll manage if we get those libs in.

Are you sure you compiled Irrlicht correctly? Have you checked the documentation and such for compiling for GLES 2?
Also, I didn't think of compiling Irrlicht itself... Maybe I should have a shot at it, as well?
