I might have fixed the battery drain problem with the gbs kernel (not sure though). But i think there still isn't any usb support with goldenleaf...
Just go ahead and test it if you want to... otherwise the stock kernel works just fine.
Well if you have a link to the kernel then sure, just flash it. (no need to wipe anything)
Alternatively you can flash the latest gbs kernel (i'm testing it right now and i see no bugs so far) or just flash the rom again without wiping data. (just dalvik and cache)
Remember:
This kernel is ONLY for LG Original 2.2, Void.#forever, devoid, miks 6.5.x, CyanogenMMatt 1.1...
