There's a third-party kernel available for this phone made by a guy on XDA named Jeboo.
I have it on my phone right now, seems to be very stable. Plus, couple this with Trickster MOD on the Google Play Store
and you can tweak this phone a bit.
I myself changed the CPU governor from OnDemand to Interactive. This has proven to be a better CPU governor in the sense that it seems to be ramping up the speed of the CPU faster than the OnDemand governor thus killing the big bad ugly lag monster.
