I'm comparing the results. In both cases, machine hangs, someone might loose
data. NOT to anyone else though.

Sure I can. I also have enough knowledge to recompile my kernel. But i don't
think i'm the only person running Breezy on a white iBook in the world.
Furthermore, what I want is a working solution of the problem, not a workaround.
Cuz the best workaround might be simply using OS X.

As I said, I've resolved the problem with closing the lid. The problem is that
there are cases (like a battery runout) when the laptop goes to sleep without my
explicit actions. And because I have a buggy charger, which somehow randomly
stops charging while i'm at home (while it works perfectly when i'm at work),
this problem hits me even harder - if I leave my laptop on overnight i can be
almost certain that in the morning I'll have to press cmd-ctrl-power to bring it
back from suspended state.

> The thermal bug could be induced by a normal user who has remote login. Not
the same sort of thing.

As I said, for me personally, this bug gets induced without any interference
from me or anyone else. Why do you resist so hard?
