Just an FYI - the battery drain on the latest version of the lean kernel is a known issue and is usually fixed by wiping your battery stats. I use this app to make it easy on myself (+ it's nice to see the real time voltage)

Battery levels can still be a bit wonky, but I'm happy with the battery performance overall.
I'm running Resurection 1.0 with 1.52 of the lean kernel. I get no force closes, but I do get the occasional reboot (likely due to the voltage/oc settings in the kernel), but my phone runs so well I really couldn't be arsed to try and fix it. Since lean kernel reboots so quickly (15-20 seconds) it's only slightly annoying.
I tried TKS a few times an always encountered horrible performance lag no matter what settings I changed with Voltage Control. Maybe it's just me, but I couldn't get it to play nice.
