The power might be controlled via a triac.  When low voltage is applied to a 
florescent bulb it's impedance/resistance is quite high, so I would suspect 
the triac is leaking and building up a charge until the point the bulb tries 
to turn on, which in turn drains the leakage current back to nothing.

Voila, Flicker!!!

I am not an EE or play one on TV, so take the idea with a boulder of salt.
