No, I was bitten before reading this and haven't had the chance to
test it. Also, my xset says I have DPMS suspend on, so I'm probably
already using the workaround. My symptoms were not a garbled display,
but a permanently turned off one, perhaps different bugs altogether.

It probably depends on your mplayer rpm. mplayer -vo help lists the
output devices:

You don't have a real choice on a fanless low-CPU-power system
relaying on the GPU's acceleration. That's what XvMC is about. :(

There is a wrapper lib that can be used to divert the XvMC
implementation at runtime. That would protect against broken (unused)
libs.
