Comment(by dsd):

 This is because geode (src/geode_dcon.c) puts the dcon to sleep (via
 sysfs) when X changes DPMS mode. And X is changing to mode 3 (DPMSModeOff)
 twice during startup, before turning it on again.

 Disabling DPMS (like XO-1.5) is probably one way to work around this, but
 I'll try and understand why X is behaving this way.
