Hi Ilia,

I applied your patch and my system now boots up. I saw an login-screen-image
from before the boot for a split-second.  apart from that, it seems to run
fine. (no stress testing done, just firefox and some gnome terminals...)


what does your patch do? increase the reported size of some of the objects?
