I did on 2.6.24
strace -ff s2ram >s2ram24.trace 2>&1
and .25
strace -ff s2ram >s2ram25.trace 2>&1
with the .24 bringing the display back and .25 not. Files are here

I have no idea how to 'disable randomization' and also not which debugging options I should have set ... tell me what things/options you need to be en/disabled and I redo the experiment.
