Hmm... I tried to install ICS Domination over Hydrogen and now it just boot loops
/Face Palm... ICS Domination isn't designed for AOSP ROMs, lol.
Yeah installing a 95% ICS like theme on pure ICS....isn't going to work

Hydrogenics is working great for me. LPS modem too. Battery drain seems very good as well.
80% after 5hrs 20mins, that's with 1hr10mins screen on time. Hydro's kernel seems to utilise Speed ranges in 100MHz increments too unlike others which use 200MHz, looking at CPUSpy I can see that deep sleep is working and the used speeds scale from 200 to 1200 nicely too.
I did set governor to On Demand from lulzactive.
