The JIT blacklist can be disabled with an environment variable... but I do not actually know how to start a program with an environment variable on Android. I'll ask around and see if there's a simple way to do it.
If not, we hope to have a build with the JIT re-enabled soon. Ideally we will fix the problem soon for all phones, but if that takes a while then we might first re-enable it for Galaxy S phones running 2.2.
