An update: I tried using the proprietary fglrx driver and that fixed the problem (though it created another one: I couldn't switch from X to a virtual terminal). Anyway, I'll see if I can find some configuration parameter for the radeon driver that eliminates the problem; otherwise I'll try to contact the radeon driver developers and seek some advice.
