On our system, using mplayer to play a movie that has 44.1KHz audio (hardware
only supports 48KHz) can cause audio stuttering if we're using OSS emulation,
but not if we're using native ALSA. Is this a known problem? Does OSS
emulation hog the CPU?

It won't as long as you do right :)
Mostly this kind of problem is the difference of parameters. Try to
reproduce the playback with the same parameters used by OSS emulation
(you can see /proc/asound/card0/pcm*/sub*/hw_params) with ALSA API.
