just sharing my experience. i noticed radio signal has improved slightly too.
welcome... to try it out... darn showp is great developing kernel, leedroid also recommending those who is looking for extreme kernel tweaks to try bricked kernel.

battery drain for 1st 10 mins after flashed bricked 0.4 is significant. but over past an hour, it only dropped 2% for me with wifi on, syncing email manually for 7-8 times, whatsapp light usage. phone is running COOL as well!

--EDIT--
@kaheng20: nope, i dont wipe dalvik nor clear cache. just flash and run!

did i say that is a practice?  lol..

let the kernel to sit in.. give a few full charge cycle to monitor the battery performance =)

a quick review of leedroid v.7.0 bricked 0.3 kernel uv -75:
1. ultra smooth
2. phone is cool, idle for 7 hrs battery drained 2%
3. sense restarted once upon exit of dolphinHD (browsing with 4 tabs for 10 mins, whatsapp simultaneously)
4. rebooted once : lockscreen > camera > snapped a photo > access gallery from camera

flashed bricked 0.4 kernel (stock setting without tweak) and running for 2 hrs plus:
1. improved responsiveness
2. phone is even cooler

will report more after trying for next few days.

are you running with yellow man? i've been suffering the same lately as well.. darn sucks but cant complain much for the price i paid.. 

btw, my phone is flying with bricked 0.5 eventhou cpu1 is offline, havent got time to read thru the bricked topic

if i wanna upgrade to leedroid ICS, which firmware to install?
Leedroid said need 3.32.401.5, but when i go to the link given it seems got so many choices ...

?? really?? i saw a post in xda from msia reporting first boot takes ages too.. my downloading speed is darn slow... ishhh
--EDIT-- it seems like an issue with the latest release..

You guys face any problem with the stock XE where you lose network connection? So in the signal bar, it'll be empty with and "X" on top of it.

How to resolve this? Quite annoying when I don't realise that the connection is lost.

cool, now that i know there is this category of users. 
yea, leedroid 7.1 with bricked 0.55 lag free governor is working fine. never experience reboot during idle / call (was on phone for 65 mins last nite). cant tell much on battery performance yet as currently running on 2nd charge cycle.

i flashed v.7.1 on top of v.7.0 without wipe.

hahahaha.. just tried and yes, it reboots.. i've been using it since yday 7pm under normal using pattern, never generated this issue so i can definitely live with it! why would you need to press the power button for so many times?

hahaha... bashing... 

if i were you, i'll flash before battery is fully charged, so that it takes shorter time to have a full charge for battery calibration upon flashing new rom and also having 100% of juice for me to rape the phone.. lol

i cant tell you how good is hagen daz is comparing to walls ice cream, until you taste both to find out which suits your taste more.

both leedroid and arhd is good in their own ways 

Yeap, that is the correct one. Do u want revert back to stock ROM?

You don't have to revert back to stock RUU to install official ICS. You just need to remove the custom recovery and replace with the stock recovery and you good to go. Follow this link on how to revert back to stock recovery
