Screen would not stay blank

[Michel Salim]

This probably has been happening for some time, but I just noticed
over the last couple of weeks that my laptop's screen never turns
itself off, regardless of Power Manager preferences.

So I ran a script that calls 'xset dpms force off' every 10 seconds.
And the result is disturbing: whether the screensaver is on or not (I
tried setting it to both Fedora Bubbles and Blank), the screen would
be on again within a few (< 10) seconds, without fail.

This is on x86_64 with a shared-memory ATI Radeon XPRESS 200M, radeon
driver from X.org. This is a driver bug, I take it?
