[Galaxy S I9000 Android Development] Coldwindofnowhere:
Well a black screen at boot is weird, i've never experienced that. About Subway Surfers, it seems that some games wont run, it could be great to post the logs here

EDIT : This game is incredibely slow to launch, but i don't see anyting related to CMA in the longs, maybe the problem comes from somewhere else ... So i think the problem comes from Zram or Swap in itself since we're getting OOM :
