Those quirks worked well in beta of Ubuntu 9.10 but now this line:
<merge key="power_management.quirk.radeon_off" type="bool">true</merge>
causes that computer hung up (with black screen) during resume from suspend.
So problem is still there (flickering screen after suspend) but now known solution doesn't work any more (at least on my computer).
I don't know what was broken in period between beta and final version.
