i'm also having battery drain with the 2411 rom and also i have some big delays(5-15 sec) with black screen whenever i open a new app.
I re flashed , empty cach,dalvik with no improvment.
My phone is gen2 160mb system 2 cache
Thanks for the update.
The following option is not available to me after flashing to cm-9-20120827-KonstaKANG-blade.zip
added option for circle battery (Settings -> System -> Status bar -> Battery status style -> Circle)
flashed, cache & dalvic wiped , rebooted.
My display lang is greek
Update FIXED !!!!!
changed language to english , option appeared, selected circle , and returned to greek
Now in greek Settings -> System -> Status bar -> Battery status style -> the radio button shows the option "hidden" but it works
